In a farm in northwest China’s Gansu province, sensors are inserted into the soil to monitor humidity, while a miniature weather station tracks wind and light conditions.

“Last year, the sunflower yield per mu (about 667 square meters) exceeded 280 kilograms, an increase of 15 percent,” said Zou Changsheng, head of the project department of the farm.

With the use of smart irrigation, bountiful harvests were guaranteed, and the water usage per mu has decreased from 650 cubic meters to 300 cubic meters, Zou added.

The irrigation water comes from the Shule River, which flows through the desert, nurturing oasis along its path. The Shule River provides irrigation water for a total of 1.34 million mu of farmland spread across 22 townships in Jiuquan, Yumen, and Guazhou county, as well as six farms.

The Shule River basin receives less than 70 millimeters of precipitation annually, while the evaporation is as high as 2,800 millimeters. How can this water-deficient river achieve intensive water conservation while ensuring proper irrigation?

“We have ‘digitized’ the Shule River,” said Zhang Farong, deputy director of the planning department of the Shule River basin water resources utilization center in Gansu province.

By leveraging geographic information systems and building information modeling, a virtual model has been constructed to simulate the river channel, canal system, reservoirs, and water gates in equal proportion, creating a “digital twin” of the river, Zhang explained.

Through large model simulation, water resource scheduling plans have been continuously optimized. Manual gate operations have been automated, enabling precise water release based on demand. The construction of high-standard farmland is advancing in sync, with integrated water and fertilizer technologies such as drip irrigation and precision fertilization, saving both labor and water. By combining data, algorithms, and computing power, the Shule River irrigation area is gradually becoming a leading example of water conservation.

These efforts to use digital technology to promote water-saving agriculture in the Shule River basin reflect China’s rapid progress in developing a digital twin system for water resources management.

“In simple terms, digital twin water resources management refers to the use of technologies such as artificial intelligence, 5G, and large models to virtually replicate natural water systems and hydraulic engineering structures on the internet. This enables the simulation of interactions between physical and virtual objects, facilitating precise forecasting, early warnings, rapid scenario simulations, and the development of contingency plans,” said Sun Chunpeng, director of the hydrological information forecasting center at the Ministry of Water Resources.

In recent years, China’s water resources sector has completed 94 construction tasks of digital twin for water resourcemanagement .

The construction of a comprehensive water monitoring system covering the Yangtze River basin has commenced, accelerating the formation of a prototype digital twin of the Yangtze River.

A digital twin Yellow River project is advancing in an orderly manner, which aims at promoting the deep integration of the real-world Yellow River, Yellow River models, and a digital twin of the Yellow River.

In the development of digital twin water networks, a framework for constructing a national backbone digital twin water network has been completed. Progress has been made in the preliminary establishment of a digital twin for the first phase of the South-to-North Water Diversion Project’s central route, and 10 provincial-level pilot areas have achieved practical results in building their digital twin water networks. Efforts are also underway to advance the construction of digital twin water networks at the municipal and county levels.

Regarding digital twin projects, continuous iterative optimization is being carried out for key sites such as the Three Gorges Dam, Xiaolangdi Dam, Danjiangkou Reservoir, and Yuecheng Reservoir. From 2023 to 2025, 49 digital twin irrigation areas will be piloted. Besides, large and key medium-sized water conservancy projects newly constructed in 2025 will launch information infrastructure, digital twin platforms, and business application systems.

Digital twin in water conservancy enable more targeted management of rivers and lakes. China’s Ministry of Water Resources has established a national key rivers and lakes ecological flow monitoring and early warning platform. This platform gathers monitoring data such as water levels and flow rates from 283 ecological flow sections of key rivers and lakes. It enables real-time monitoring and early warning for 235 ecological flow control sections across 165 key rivers and lakes, as well as 65 water allocation sections.

A national water use management platform has been set up, allowing for dynamic monitoring of violations such as excessive water use, exceeding control limits, and lack of measurement for water users with permits. Up to now, 131,000 online monitoring points and 551,500 offline monitoring points nationwide have been connected to the platform.

Digital twin in water conservancy enable more science-based management of water conservancy projects.

In water conservancy engineering construction management system, information from over 40,000 enterprises, more than 1.07 million professionals, and over 420,000 project performance records and credit evaluations in the water resources industry have been consolidated.

In the water resources project operation management information system, electronic archives of over 90,000 reservoirs across nine industries, including water conservancy, energy, and transportation, have been shared.

In the rural water resources and hydropower information management system, basic and operational information for 520,000 centralized water supply projects, 42,000 small hydropower stations, and 7,326 large and medium-sized irrigation areas are updated annually, with a daily average of over 3,000 visits.

Shantou taps new growth momentum via AI token exports

Published

on

By Li Gang, People’s Daily

As artificial intelligence (AI) accelerates the transformation of global industries, a new form of digital trade is emerging in the southern Chinese city of Shantou: exporting computing services measured not in physical goods, but in AI tokens.

In late April, Shantou, Guangdong province completed full-chain verification for what has become known as “token exports” — a model in which computing power remains within China while high-value AI services are delivered to overseas users. Within just one month, average daily token usage surged from 100 million to the tens-of-billions level.

The practical application of this model is already well underway. 

Recently, when a user in Singapore activated an AI-powered toy and gave a simple command — “Tell me a fairy tale” — the spoken command traveled through the network directly to a dedicated overseas computing zone inside a computing center in Shantou. 

Local deployed AI agents wrap up speech recognition in under one second and craft custom story content, firing the finished audio back to the Singapore-based toy device in as little as 0.1 seconds.

The user repeated the process multiple times, eventually listening to five stories in total. Approximately 100,000 tokens were consumed during the interaction and billed in real time at a rate of 2 yuan ($0.3) per one million tokens.

When payment arrived, a complete commercial cycle was achieved, marking the successful realization of Shantou’s “token export” model.

Tokens represent the smallest discrete calculation unit for large AI models to process information. They have become a key indicator of intelligent computing capacity and, increasingly, a new carrier of value in the digital economy.

Inside the China (Shantou) Pilot Zone for Economic and Cultural Cooperation with Overseas Chinese, token exports are already transforming the economics of electricity.

Today, overseas users across multiple countries and regions in Southeast Asia are accessing token services generated in Shantou.

“Data flows in from abroad and all processed outputs head back overseas, with zero compromise to end-user experience,” explained Cai Qichen, an engineer at the Shantou Branch of wireless carrier China Mobile. “Token costs have already been integrated into product service packages, making future usage more convenient.”

According to estimates from toy manufacturer SHOWMAC based in Shenzhen, Guangdong province, using Shantou’s computing services reduces costs by more than 30 percent compared with directly purchasing overseas computing resources.

Meanwhile, inside computing centers, turning electricity into AI tokens delivers dramatic value appreciation. A kilowatt-hour of electricity, which comes at a cost of roughly 0.5 yuan($0.07) , can be transformed through AI computing into tokens and then exported at a price of 11 yuan($1.6), representing a twenty-two-fold increase.

As one of eastern Guangdong’s major offshore wind power bases, Shantou has already connected 1.2 million kilowatts of installed capacity to China’s power grid.

The electricity itself does not need to cross borders. Computing power remains within China. What gets exported instead are high-value digital services, turning electricity into a form of hard currency for cross-border digital trade.

Ultra-low network latency forms the technical backbone making token exports feasible.

“More than half of China’s outbound bandwidth carried by international submarine cables lands in Shantou, and the city is also home to five undersea trunk cables linking destinations worldwide,” said Hong Zhebin, chief technology officer of the international submarine cable landing station operated by the Shantou branch of wireless carrier China Telecom.

“The latency between Shantou and Singapore is only 32.7 milliseconds, quicker than the blink of an eye,” Hong added.

Hong Yu with the Shantou Branch of China Mobile, added that Shantou’s overseas computing services offer stable response speeds, regulatory compliance, and substantial cost advantages.

“Our pricing is only 1/3 to 1/2 that of mainstream international platforms, while customer retention exceeds 70 percent,” Hong told People’s Daily.

Yet building a complete end-to-end system is only the starting point. Shantou is now attempting to transform itself from a transit city for digital infrastructure into an ecosystem hub.

Leading computing companies and developers are gathering rapidly. Pilot platforms have passed acceptance reviews. Commercial closed loops have already emerged in applications ranging from AI toys to intelligent manufacturing, with large-scale operations expected soon.

Shantou’s Chenghai district has long been known as the “toy capital of China.” As AI becomes increasingly integrated with the toy industry, the city has launched an AI toy innovation center and the Shantou AI Laboratory, striving to become the “AI toy capital of China.”

At the exhibition space of one local tech firm sits Amy, an AI desktop robot capable of fluid multilingual conversation.

“It is equipped with a multilingual intelligent voice interaction system capable of real-time recognition and conversation in dozens of languages,” said the company’s general manager Chen Ruifeng.

The technology has already been integrated into multiple AI toy products exported to countries including the United Kingdom, Russia, and Japan.

Shantou’s token export model allows AI toy manufacturers to access domestic large language models at costs far below those of overseas alternatives.

“The cost of using overseas AI models can be dozens of times higher than domestic models,” Chen said. The company’s AI toys currently run on Chinese large models including DeepSeek and Doubao.

“Token exports have significantly increased both product value-added and international competitiveness,” he said.

The Shantou branch of wireless carrier China Unicom, together with a Guangdong-based tech firm, has established dedicated lines connecting Shantou and Vietnam, delivering cross-border computing services to Aachen Sv, a Chinese-invested fiber-optic company operating in Vietnam.

Vietnamese users accessing large models such as DeepSeek and Qwen experience extremely low latency with zero packet loss. “In less than a month, more than a dozen companies have approached us for consultations,” an employee of the Guangdong-based tech firm said.

Meanwhile, the Guangdong branch of China Mobile has launched an OpenClaw intelligent agent framework, providing integrated AI service packages that allow traditional toys to complete intelligent upgrades in as little as 15 days.

From toys to textiles, cross-border e-commerce, and high-end manufacturing, tokens are increasingly becoming the digital fuel powering Shantou’s industrial upgrading.

Sanxingdui Museum transforms ancient relics into interactive experiences

Published

on

By Song Haoxin, People’s Daily

What if museum visitors could truly interact with cultural relics rather than merely observe them through glass displays? At the Sanxingdui Museum in southwest China’s Sichuan province, a specially designed interactive hall is revolutionizing cultural engagement.

Within this 1,300-square-meter space, nearly every exhibit invites touch, operation, or participation. Visitors immerse themselves in installations inspired by the ancient Shu civilization, blending education with entertainment.

By trying on replicas of headwear on bronze statues discovered in Sanxingdui Ruins, for example, visitors can not only take photos of themselves but also learn about the symbolic meanings behind different headpieces. 

Guests can don replicas of bronze statue headwear from the Sanxingdui Ruins, learning their symbolic meanings while capturing photos. Augmented reality allows dancing alongside virtual Sanxingdui figures for social media sharing. A creation zone even enables “time travel” to experience ancient bronze-casting and construction techniques.

These innovations transform traditional museum visits, offering deeper cultural understanding through hands-on interaction. “This hall emerged from extensive brainstorming,” explained Zhu Yarong, deputy director of the management committee of the Sanxingdui Ruins site. 

“We’re transitioning from passive relic viewing to interactive engagement, bridging the gap between audiences and history.”

Previously, museum experiences were largely one-directional with limited engagement. Visitors viewed relics through display cases, usually stopping mainly to take photographs, with relatively limited forms of engagement. By liberating artifacts from display cases into interactive settings, Sanxingdui is pioneering a shift from didactic presentation to open cultural dialogue.

Traditional exhibition spaces remain popular, while digital innovations attract growing interest. A VR project employs digital twin technology to recreate 1:1 scale excavation sites — complete with protective shelters and cabins — placing visitors at the archaeological forefront.

Another project, Heaven and Earth Echoes — Sanxingdui Panoramic Sound and Vision Digital Art Theater, features an interactive panoramic LED dome with a diameter of 20 meters and a resolution approaching 16K. The massive dome creates a deeply immersive atmosphere. By waving digital torches in their hands, visitors can trigger sacred birds to circle above them across the dome, experiencing the ancient Shu civilization through an interplay of sound and imagery.

“The digital technology made me feel as if I were racing across the Mamu River. That sense of traveling through time was incredible,” said Hao Yong, a tourist from southwest China’s Chongqing municipality who came specifically to experience a virtual reality program.

From passive observation to active participation, Sanxingdui Museum continues introducing new interactive experiences that transform cultural relics into living carriers of dialogue and engagement, helping keep the sparks of Chinese civilization alive for new generations.

A living testimony about MKA: The Aondoakaa that I know Written By Brahms Tor-Ikuan

Published

By

My people of Benue State,

I am not speaking to you today as a politician. I am speaking as a brother whose family was held up by Chief Mike Kaase Aondoakaa, MKA, when we had no one else to hold onto.

My elder brother, Verem Ukaa-Ikuan, was not just my blood. He was a very dear and close friend to Chief MKA. When my brother fell ill and was diagnosed with liver damage caused by poisoning, MKA didn’t treat it as someone else’s problem. He took it on as his own.

He worked closely with Verem during his time as Attorney General of the Federation, and when the sickness came, he moved immediately. Searches were conducted, and Apollo Hospital in India was earmarked for a liver transplant. Every travel arrangement was made personally by Chief MKA.

But we hit a wall. Verem was too weak to fly a long commercial flight. Only an air ambulance could get him to India alive. At that time, there was only one functional air ambulance in the entire country, owned by Julius Berger. It was completely out of reach for even the most high-profile citizens.

Chief MKA went all out. He did not give excuses. He did not delay. He used every connection and every ounce of influence he had to secure that air ambulance for my brother.

On the day it was secured, Barr. Terna Yaji, his Senior Special Assistant, called me a few minutes after 6pm. He told us to prepare Verem for departure and take him to Makurdi airport very early the following morning. I informed him, my brother passed on at exactly 6 o’clock a few minutes ago. I told Barr. Terna Yaji, and I saw a devastated MKA.

During the burial, Chief MKA was out of the country on national assignment. He was pained that he could not be there physically. His entire team, led by the late Onov Tyuulugh, represented him fully. And his message to us at the burial has never left me:

“If death were law, as the Attorney General, a law would have been made no matter what to ensure Verem will just not die but live forever.”

That is who Mike Kaase Aondoakaa is when nobody is watching. He does not abandon his people. He does not forget. He stood with our family then, and he has stood with us till date.

Now he is asking for the chance to govern Benue State.

Benue needs a governor with a heart like that. A governor who fights for you even when there’s no political gain. A governor who sees you as family, not as a vote.

I am standing with Chief Mike Kaase Aondoakaa for Governor of Benue State.
For compassion that moves to action.
For loyalty that does not fade.
For leadership that proves itself in the darkest hour.

Join me. Let us give Benue a leader who has already shown what he will do for us.

God bless Chief Mike Kaase Aondoakaa.
God bless Benue State.

Brahms Tor-Ikuan, a beneficiary of MKA’s benevolence writes from Makurdi
