Editor's note:Thursday marks the 65th anniversary of the emancipation of serfs in the Xizang autonomous region, when democratic reform in 1959 ended feudal serfdom and freed some 1 million serfs that accounted for more than 90 percent of the region's population. This page is dedicated to showing the livelihood improvements of Tibetan people living on the plateau.

After a video of a pressure cooker exploding went viral in May 2022, authorities in Lhasa, capital of the Xizang autonomous region, decided to take action.

Xizang is commonly referred to as "The roof of the world" due to it being located on the world's highest plateau with an average altitude of 4,000 meters above sea level. Due to this high altitude, the air is thinner with less oxygen, so cooking takes longer. As a result, pressure cookers are often relied upon for faster, more convenient and safer food preparation.
