What should I do if I feel chest tightness while traveling in Shangri-La?

It’s okay. The altitude of Shangri-La is also 3,000 meters, so it’s a bit high. Be careful not to shout loudly, do not walk or run fast or do anything that consumes energy. Drink a few cups of butter tea, go to the drug store to buy some Rhodiola rosea capsules, and generally rest for a day or two. If the reaction becomes more severe, go to the pharmacy to buy glucose injection and take one orally every few hours.

If it is not too serious, it is best not to take oxygen or go to the hospital. You will become dependent and you will have to carry oxygen when you go to the plateau in the future.
