Perhaps you should try some spelling variations:
cheng chan » cheung chan, cheng han, cheng zhang
chan ming » kian ming, chan eng, chan fong
ming wong » ming kong, ming hung, ming qing
wong shiu » wong siu, cong shu, song shin
li cheng » li chen, xi cheng, lei sheng
qian yan » qian jun, qian yi
nan yan » nan ya, wang yan, dan yang
wang » wing, lang

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 OR wan) ((nan yan) OR (qian yan)) li cheng chan ming wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) ((nan yan) OR (qian yan)) li cheng chan ming wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((nan yan) OR (qian yan)) li cheng chan ming wong shiu ;*.
