The DNS servers for China Telecom have always been horrible, but I've noticed they've gotten considerably worse lately(probably on purpose).
For example if you load a website like example.com it might take ten tries. But if you add www and load www.example.com it will only take two or three tries.
I have two servers that hardly ever load in China. One is hosted on DigitalOcean and the other on OpenShift. Once I change the computer to use a different DNS server they then load 90% of the time instead of 10% of the time.
The photo has to have some sort of police registered photo or something.
I don't remember what it's called exactly, but they will just tell you to do it at the photo place next door.
They will give you the police registration document with a sheet of photos. It also expires, but it's cheap. I think it took 10 minutes or so for them to take the photos, print, and cut them. They do them in batches. The room isn't big so take an umbrella if you want to wait outside if it's rainy.
Seems to be pretty hit or miss. First time I went there the pizza and hamburgers were great. 2nd time the pizza was terrible, and the hamburger was ok. 3rd time the pizza was ok, but people were smoking inside by the time we left. Guess the no smoking policy is not enforced.
