Perhaps you should try some spelling variations:
hyoung yan » kyoung yang, hyoung gun, kyoung yun
yang vinh » yang jin, sang minh, yang jing
yang jie » yang jin, yang di, yang jui
yan hua » tan hua, ya hua, wang hua
hua ren » hua chen
long du » long d, long do, long run
wang » wing, lang

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 OR wan) hyoung yan hua ren ((yang vinh) OR (((yang jie) OR (shang jin)))) long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wan) hyoung yan hua ren ((yang vinh) or (((yang jie) or (shang jin)))) long du ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wan) hyoung yan hua ren ((yang vinh) or (((yang jie) or (shang jin)))) long du ;*.
