Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yulu chen » yu chen
yong yan » yang yang, dong yang, ying yang
yu cheng » yu chen, _ cheng
chan eng » chan fong, chan kang, chan ming
eng chun » tang chun, wang chun, wong chun
chun h » chung h, chun _, chun i

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 yong yan ((yulu chen) OR (yu cheng)) chan eng chun h ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yan ((yulu chen) OR (yu cheng)) chan eng chun h ;*.
