Will drunkenness occur when you return to Chengdu from Lhasa?

yes. According to official website, a horse-beehive tour, Lhasa is a high-altitude area, while Chengdu is a low-altitude area. The food eaten in Lhasa is essentially different from that in Chengdu. When you return to Chengdu from Lhasa, your body needs constant adaptation, and you will get drunk. Drunk oxygen is due to the fact that people's body has just adapted to the low oxygen environment in the plateau and re-entered the area with relatively high oxygen content, which will lead to discomfort again, resulting in fatigue, weakness, lethargy, chest tightness, dizziness, diarrhea and other symptoms.
