I don't know what your so-called formal standard is. Longhua itself has no decent bar. It is a relatively glamorous and large-scale one. It is also located in industrial and commercial registration. It has been 4-5 years since it opened, and the security situation is unknown. For example, the disco on Tianlong Avenue near Longhua Bus Station is glamorous, luxurious and legally registered, but the security situation inside is still very poor. If you are a good girl or an otaku, I suggest not to get high!
