I'm going to work as a waiter in Beijing Wuzhou style KTV. Is the salary reliable? Is it safe?

Wuzhou style is near the Olympic Sports Center, belonging to Beichen Group, next to five-star hotels Wuzhou Hotel and Crowne Plaza Wuzhou Hotel, which is very good. Many of our meetings are held there. KTV is next to two five-star hotels, and the guests who go to spend money are rich Chinese and foreign people who come to Beijing for meetings or tourism. The wage guarantee is very reliable. Of course, you must sign a formal contract.
