Beijing: In which district do you go through the social security formalities?

I am also in Chaoyang Chaoyang Social Security Bureau, and I have been changing the way to get the number. At that time, I had to wait in the lobby for two hours, and then there was no green passage. Now I am taking the number online, and I have to wait for the base number approved in the afternoon to start taking the number. There are too many problems in Chaoyang social security online application system, and I want to improve it.
