Perhaps you should try some spelling variations:
yulu cheng » yu cheng, yuan cheng
yulu chen » yu chen
chan kang » chung kang, chan fong, chan jan
chung chi » chung h
chan eng » chan fong, chan ming, han en
di gang » ii gang, i gang, li gang
d gang » 2 gang, _ gang, b gang

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 ((di gang) OR (d gang)) ((yulu chen) OR (yulu cheng)) ((chan eng) OR (chan kang)) chung chi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((di gang) OR (d gang)) ((yulu chen) or (yulu cheng)) ((chan eng) or (chan kang)) chung chi ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((di gang) OR (d gang)) ((yulu chen) or (yulu cheng)) ((chan eng) or (chan kang)) chung chi ;*.
