What are the earliest nightclubs in Changchun?

My eldest brother was famous in the early days of Changchun. The earliest ones in Changchun should be Didi at the main entrance of Changying and Lan Kwai Fong at Lucky Hotel, followed by Qianrenhe People's Square in Cultural Square, the Oriental Pearl Tower under Hualian on Sanma Road, and by the way, there is also the west of Erdian Store. At that time, it was collectively called (disco)?
