Perhaps you should try some spelling variations:
chan kang » chung kang, chan eng, chan fong
yan wang » yuan wang, yang yang, qian wang
yang jun » yang jui, pang jun, yang judy
yang jin » yang jie, ying jin, shang jin
wong yue » wang yue, hong yu
dan hua » tan hua, wang hua, dong hua
hua ren » hua chen

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: ((yan wang) OR (chan kang)) dan hua ren ((yang jun) OR (((yang jin) OR (yang di)))) wong yue ;~.
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (chan kang)) dan hua ren ((yang jun) or (((yang jin) or (yang di)))) wong yue ;*.
