Perhaps you should try some spelling variations:
chung tong » chung chong, chung mona, phung tung
chen tong » chen rong, chen yong, chen yang
qian yan » qian jun, qian yi
yan yang » yang yang, yao yang, dan yang
yang jui » yang judy, yang di, yang xi
keong su » rong su
jeong su » jeong _, jeong mi, jeong 情

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: qian yan yang jui ((chen tong) OR (chung tong)) king ((keong su) OR (jeong su)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan yang jui ((chen tong) OR (chung tong)) king ((keong su) or (jeong su)) ;~".
• Adding a wildcard symbol may retrieve word variants: qian yan yang jui ((chen tong) OR (chung tong)) king ((keong su) or (jeong su)) ;*.
