/kloc-I want to travel to Tibet in early February and ask my relatives for advice.

There are ways to enter Tibet by plane, train, car, bicycle and on foot. Consumption depends on the individual, off-season, but because it is winter, some places are not convenient to go. I suggest you pay attention to some people who travel in Tibet on the Weibo and learn more about them. I met a man who has been to Tibet many times. He said he could go at any season. But you must know something about the weather conditions you may encounter. If it really doesn't work, just bask in the sun in Lhasa.
