I stayed in Saga at an altitude of 4,500 for four days.

The first time I went to Tibet, I didn't feel very good. It's okay. Take more exercise.

I spent eight days in Tibet, the first two days in downtown Shigatse at an altitude of 3,800, the middle four days in Saga County at an altitude of 4,500, and the last two days in Shigatse.

I have been to Ganzi sertar county before, with an altitude of 3,800. My body can adapt, but I haven't tried it at the altitude above.

Speaking of the overall feeling, Shigatse at an altitude of 3,800 is much more comfortable, but it is really unbearable at an altitude of 4,500.

When choosing a hotel, you must choose a hotel with oxygen, breathe for an hour or two before going to bed (be sure to unplug it when sleeping), and fill up the humidifier of the hotel before going to bed. Scientific theories such as eating rhodiola in advance are of little use.

I went to more than 4000 places, and the oxygen content in the air was less than 50%. In the first day or two, you can choose the oxygen bottle in the hospital, and there are people in the hotel who can help you with things.

You need to apply for a border card to go to some places. You need to ask before you go, otherwise the checkpoint will not let you through. The control is also relatively simple. If it goes well, it will be done in ten minutes.

You must buy sunglasses if you drive! ! Otherwise, I can't stand the direct sunlight! !

When we go, we should try the local Tibetan restaurants, because Tibetan restaurants are really cheap. We only need 12 yuan for a cup of sweet tea and 18 yuan for a bowl of mixed rice in Saga. You can sit all afternoon, and three people spent 90 yuan for half a day.

No bathing for the first four or five days. Wait till you get used to it.

Be sure to drink more water! !

If you catch a cold, you must come back. Never catch a cold. Yes, it is because of this pleasure that I returned to Chengdu.
