We should pay attention to whether beef is delicious. I don't think anyone can compare with yak meat on the Qinghai-Tibet Plateau. Just drink mineral water and eat Cordyceps sinensis. I grew up in a pure natural environment at an altitude of about 5000, and the meat is delicious. Many foreigners from coastal areas will come to eat yak meat here. It's no exaggeration to say that you haven't eaten yak meat on the Qinghai-Tibet Plateau.
