Perhaps you should try some spelling variations:
wang yidan » wang yan
chih hang » chin chang, shih huang, chih yung
hang sing » hang seng, muang sing, yang using
sing tong » sing kong, xin tong, using tongue
wang qin » wang lin, wang qiao, wang jing
yang jin » yang jie, yang jun, ying jin
tong hui » wang hui
wang li » wang lei, wang lin, tang li
yang li » yang lin, yang di, yang xi

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: wang yidan ((((((wang li) OR (wang qin))) OR (yang jin))) OR (yang li)) chih hang sing tong hui ;~.
• Adding a wildcard symbol may retrieve word variants: wang yidan ((((((wang li) or (wang qin))) or (yang jin))) or (yang li)) chih hang sing tong hui ;*.
