Perhaps you should try some spelling variations:
wang yidan » wang yan
shih huang » chih hang
huang sing » huang jing, huang ting, huang ying
sing tong » sing kong, xin tong, using tongue
wang lin » wang li, wang qin, yang lin
yang jie » yang jin, yang jui, yang xi
tong hui » wang hui
yang li » yang lin, yang xi, yang yi

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 lin) OR (yang jie))) OR (((yang li) OR (yang di)))) shih huang sing tong hui ;~.
• Adding a wildcard symbol may retrieve word variants: wang yidan ((((wang lin) or (yang jie))) or (((yang li) or (yang di)))) shih huang sing tong hui ;*.
