Because I have been to the plateau, I have lost a lot of memory, thinking, attention, discrimination and consciousness since I came back. Before I went to the plateau, my brain activity room was quite active, and after I came back, it was almost a dead ember. Although this is a bit exaggerated, I already feel like dying embers, because that kind of extremely active brain movement is hard to get back, and I don't want more people to be like me, so I gave the most real reply to this answer. Don't believe the precautions for going to the plateau on the Internet. Those precautions are really useful, which will prevent you from suffering from strong altitude sickness, but no one pays attention to the damage to your brain intelligence at all, and no one gives advice. They must be considered before going to the plateau, otherwise the brain activity will be reduced by more than half! ! !
