"This initiative also helps drive the economic development of the Xizang region and provides residents with more convenient and efficient cooking tools, contributing to the improvement of people's living standards," he said.

Gao said the company produces an average of 2,000 plateau pressure cookers a day and around 50,000 a month, and has sold more than 700,000 in total.

The government has provided thousands of these pressure cookers free of charge or heavily discounted to residents.

"Thanks to the subsidies, our villagers could buy the pressure cookers for only 100 yuan last year, while it would cost nearly 900 yuan if bought in a regular store," said Yeshi Drolma.

"Due to the high altitude, low air pressure and low boiling point in Xizang, even with a strong fire, the water temperature only reaches around 80 C. Therefore, a good pressure cooker is an essential cooking utensil for the local population," she said.
