Perhaps you should try some spelling variations:
chan ming » kian ming, chan eng, chan fong
chen chan » chen chuan, cheung chan, chen chung
kong saur » kong sar, kong siu, wong sau
kong your » kong young, knowing your
yan yuan » yan guan, fang yuan, nan yan
fan guon » gan guan, yan guan
li chen » yi chen, jui 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: lang ((yan yuan) OR (fan guon)) li chen chan ming ((kong saur) OR (kong your)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan yuan) or (fan guon)) li chen chan ming ((kong saur) OR (kong your)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yan yuan) or (fan guon)) li chen chan ming ((kong saur) OR (kong your)) ;*.
