Hainan to Lhasa: 1. Crossing the sea and taking a train from Guangzhou to Lhasa: It takes a long time and requires patience, but you can enjoy the beautiful scenery of the south (Guangdong and Hubei), the north (Henan and Gansu) and the plateau (Qinghai and Tibet) all the way. Flight: If it's cheap, transfer from Guangzhou to Lhasa, or fly to Chengdu first and then to Lhasa: it's time-saving and convenient. Of course, off-season (winter) air tickets are greatly discounted! ~ hehe ~ 1
