You are quite right bro WB.
I recalled years ago, used to go to a ktv in Shanghai, the mms is a SYT and her fleet of girls were also quite nice.
In China, especially in the southern part, the girls started working when they were 17,18. By the time when they were 20 or older, some already were becoming mms. They probably earned enough and stopped working in the trade by late 20s.
Singapore, on the other hand, got all the really elderly ones in their 30s,or even 40s. Good grief. Hard to have SYT that can fit your criteria. Unless you don't mind Viet. There's one ktv near Jalan Besar, it's called the First Club, used to have rather young and wild Viet.
