Are beer promoters in Harbin nightclubs safe? What are the working hours?

What is the concept of security referred to by LZ? Simply put, safety is too broad. Let's just say that you mainly sell the beer from the enterprise that pays you and send it to the guest's private room. There must be a commission. No one will do this without commission. Life safety is safe in 99.99% cases, and few guests will cause trouble because of the waiter unless you are really beautiful! ! ! ! ! !

Usually 18 to 2 o'clock.
