Perhaps you should try some spelling variations:
hwang byoung » wang hyoung, kang young
lang hyoung » wang hyoung, kang young
hua rene » hua ren, juan rene
rene yan » ren yan, rene ten, see yan
long shu » cong shu, tong shui
yan hua » tan hua, ya hua, wang hua
yan jiu » yang jie, yang jin, pang jiu
long du » long d, long do, long run

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: ((lang hyoung) OR (hwang byoung)) yan hua rene yan jiu ((long shu) OR (long du)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang hyoung) or (hwang byoung)) yan hua rene yan jiu ((long shu) OR (long du)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang hyoung) or (hwang byoung)) yan hua rene yan jiu ((long shu) OR (long du)) ;*.
