Quadriplegic and bedridden in a prefabricated home, 36-year-old Li Xia (黎夏) can only move one finger and one toe — yet he runs a high-tech farm in southwestern China using sensors, cameras and a computer.
Li, who has a genetic degenerative condition that progressively weakens muscles, relies on a ventilator permanently connected to his windpipe to breathe, but grows celery with the help of his 62-year-old mother.
From his bed, he operates four greenhouses that lie 10m away via a program he created and a computer screen hanging above him on an adjustable arm.

“Through this microcomputer and the program I developed, and a mobile app, I can monitor various data points from the farm, such as temperature, humidity, nutrient solution concentration and pH levels,” Li told reporters. “With the cameras, I can see if the water pump is working or if the fans are running.”
With the one finger he is able to move, he controls the on-screen cursor using a trackball.
“To click, I use a flex sensor attached to my toe,” Li said from his home in Shiping village, near the southwestern city of Chongqing.
Duchenne muscular dystrophy, which he has, is an incurable genetic disease that affects almost exclusively males, at a rate of one in 5,000 births.
Over the years, it causes muscles to weaken, increasing the risk of falls, before paralysis sets in, affecting cardiac activity and breathing.
Until the early 2000s, boys with the condition rarely lived beyond their teens, but with comprehensive care, survival into the 30s and even 40s is possible.
Li, who was once able to get around in a wheelchair, experienced a sudden medical crisis in 2020 when he was 30 years old. He fell into a coma, became incontinent and quadriplegic.
“I was devastated, but after a few months, I pulled myself together and looked for things that made sense,” he said.
He discovered hydroponics, an innovative cultivation technique by which vegetables are grown not in soil, but in a solution of water enriched with essential nutrients.
Partially automated, it requires little manual labor, allows for crops to be precisely controlled and ensures good yields.
“I grew up in the countryside, so I’ve always been in contact with seeds, soil and vegetables,” Li said. “I also love digital technologies and programming. I realized I could combine the two.”
Li taught himself computer programming and learned how to design a circuit board.
His case is in many ways similar to others with severe neuromotor disorders, such as British physicist and cosmologist Stephen Hawking, who was confined to a wheelchair and could only communicate through a voice synthesizer.
Or Jean-Dominique Bauby, who was paralyzed after a stroke and authored his 1997 book The Diving Bell and the Butterfly by blinking his left eye, the only movement he could still control.
For the farm tasks involving manual labor, Li is reliant on his mother, Wu Dimei (吳弟美).
“She is my arms and legs, and I am her brain,” he said.
Li explains what needs to be done and supervises her work in the greenhouses via a video link to his smartphone.
Wu operates tools, measures out fertilizer, installs equipment and connects cables.
In addition to farm work, she provides for her son day and night, including cooking and cleaning the ventilation tube in his windpipe.
“I don’t have time to rest,” Wu told reporters.
Even with the help of her daughter, who regularly helps bathe her brother, Wu only sleeps three to five hours a night.
“But it’s worth it,” said Wu, who is divorced. “It may not seem like it, but our family is quite happy.”
They mainly rely on the income of Li’s sister, who works, and their mother’s pension.
Li said he saw the high-tech farm as a “niche” with “great prospects,” and hoped to provide his family with a livelihood.
“If I succeed, it would allow me to fulfil a dream, but also to earn money and improve our living conditions,” he said.
They moved to a prefabricated portable home in 2022, and his celery is sold to a local supermarket chain.
“We’re not making a profit yet, but my dream is to expand this farm, turn it into a successful business, produce more and earn more,” said Li, who embarked on his venture in 2022. “My motivation is to see our vegetables grow, be harvested, sold and end up on people’s plates.”
Singapore-based ride-hailing and delivery giant Grab Holdings Ltd has applied for regulatory approval to acquire the Taiwan operations of Germany-based Delivery Hero SE's Foodpanda in a deal valued at about US$600 million. Grab submitted the filing to the Fair Trade Commission on Friday last week, with the transaction subject to regulatory review and approval, the company said in a statement yesterday. Its independent governance structure would help foster a healthy and competitive market in Taiwan if the deal is approved, Grab said. Grab, which is listed on the NASDAQ, said in the filing that US-based Uber Technologies Inc holds about 13 percent of
The domestic unit of the Chinese-owned, Dutch-headquartered chipmaker Nexperia BV will soon be able to produce semiconductors locally within China, according to two company sources. Nexperia is at the center of a global tug-of-war over critical semiconductor technology, with a Dutch court in February ordering a probe into alleged mismanagement at the company. The geopolitical tussle has disrupted supply chains, with some carmakers reportedly forced to cut production due to chip shortages. Local production would allow Nexperia’s domestic arm, Nexperia Semiconductors (China) Ltd (安世半導體中國), to bypass restrictions in place since October on the supply of silicon wafers — etched with tiny components to
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday received government approval to deploy its advanced 3-nanometer (3nm) process at its second fab currently under construction in Japan, the Ministry of Economic Affairs said in a news release. The ministry green-lit the plan for the facility in Kumamoto, which is scheduled to start installing equipment and come online in 2028 with a monthly production capacity of 15,000 12-inch wafers, the ministry said. The Department of Investment Review in June 2024 authorized a US$5.26 billion investment for the facility, slated to manufacture 6- to 12nm chips, significantly less advanced than 3nm process. At a meeting with
Taiwan’s food delivery market could undergo a major shift if Singapore-based Grab Holdings Ltd completes its planned acquisition of Delivery Hero SE’s Foodpanda business in Taiwan, industry experts said. Grab on Monday last week announced it would acquire Foodpanda’s Taiwan operations for US$600 million. The deal is expected to be finalized in the second half of this year, with Grab aiming to complete user migration to its platform by the first half of next year. A duopoly between Uber Eats and Foodpanda dominates Taiwan’s delivery market, a structure that has remained intact since the Fair Trade Commission (FTC) blocked Uber Technologies Inc’s
