How about being a policeman in Urumqi, Xinjiang?

First of all, what unit do you see as a policeman? What kind of police? Being a policeman in Xinjiang is still hard compared with the mainland. Because of the special location, I often work overtime on duty to prepare for war. The salary is not very high, but compared with other places in Xinjiang, being a policeman in Urumqi is not bad.
