Most of what actually goes wrong on a trip to this part of China is administrative rather than physical: whether you are allowed to drive, whether you need a permit, how you pay for anything, how you get in. These pages answer those questions directly, and they say plainly when the answer depends on your passport.

Apps and getting things done
Ten pages on the practical machinery of being here: the apps that run trains, taxis, food, hotels and maps — and how to use them when you do not read Chinese.
Where these answers come from
From driving these roads and dealing with the consequences, not from a guidebook. The counts are mine — how many guests have had altitude trouble, what I have seen at rental counters in Chengdu. Where a figure comes from somewhere else, it says so on the page.
The one thing you should never take as settled is entry policy: visa-free lists and permit rules in this part of China have changed several times in the past two years, and they will change again. Each page says what to check and where.
These pages are published in the site's languages as each one is translated — use the language menu at the top to switch. None of these answers involves a price, because I don't publish prices here.
