Perhaps you should try some spelling variations:
yulu cheng » yu cheng, yuan cheng
dong yang » dong hoang, wang yang, yang yang
yulu chen » yu chen
eng chung » fung chung, kung chung, tung chung
yong yan » yang yang, ying yang, yong yoon
chan eng » chan fong, chan kang, chan ming
chung h » chun h, chung _, chung hee

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 ((yong yan) OR (dong yang)) ((yulu chen) OR (yulu cheng)) chan eng chung h ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yan) OR (dong yang)) ((yulu chen) or (yulu cheng)) chan eng chung h ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yan) OR (dong yang)) ((yulu chen) or (yulu cheng)) chan eng chung h ;*.
