Perhaps you should try some spelling variations:
dang wang » wang yang, dang anh, dang hung
wang yong » wang yang, wang hyoung, wang yan
hua irene » hua ren
chang min » zhang ming, chang mae, chan ming
yong hua » dong hua, ying hua, wang hua
yang lin » yang jin, wang lin, yang liang
yang li » yang di, yang xi, yang yi
hong yu » wong yue

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: dang wang yong hua irene ((chang min) OR (((yang lin) OR (yang li)))) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dang wang yong hua irene ((chang min) or (((yang lin) OR (yang li)))) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: dang wang yong hua irene ((chang min) or (((yang lin) OR (yang li)))) hong yu ;*.
