I'm from Yuzhou, Henan, and I'm going to travel to Tibet by train at my own expense. Any suggestions?

Take some thick clothes and pay attention to prevent altitude sickness.

BUFF Fu Ba is one of the successful products for relieving altitude sickness and resisting fatigue. He is a high altitude anoxic responder, traveling at high altitude, driving long distances and staying up late to work overtime.

Exercise, fitness, fatigue relief, etc.
