I want to travel to Tibet and prepare for an oxygen trip. I don't know why I saw a solid oxygen called Taiji Fresh Oxygen recently.

Plateau tourism is still a bit risky. The key depends on everyone's physique. There must be some people who can't get up and down every year, but this is a small probability. Taiji oxygen fixation is very small, so it can be put in a pocket and can hold 30-40 liters of oxygen. It is also going to travel on the plateau. You can use it when you are weak or uncomfortable. Just pull the tab. If you want to cross Ali, Hoh Xil and climb Mount Everest, you'd better prepare one honestly and don't take your life seriously. The plateau is cruel. It's cruel.
