I don't know what you call formal standards? Longhua itself is not much of a decent bar, charm four shot is still a relatively large-scale one, but also in the business registration, opened also 4-5 years, but the security situation is not known, like charm four shot not far away near the Longhua bus station near the Tianlong Avenue Disco, the size of the luxury, legally registered, but inside the security situation as usual is very bad. If you are a good girl or geek, it is recommended not to go to hi!
