Perhaps you should try some spelling variations:
wang yidan » wang yan
chen chan » chen chuan, cheung chan, chen chung
chan fong » chew fong, chan eng, chan kang
fong chan » jong chan, long chain
wang ban » wang yan, wang dan, wang yang
ban chen » jane chen, jean chen, kang chen
chan wei » chen wei, chan hei, han wei

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yiqian) OR (wang yidan)) wang ban chen chan fong chan wei ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yiqian) OR (wang yidan)) wang ban chen chan fong chan wei ;*.
