Perhaps you should try some spelling variations:
wang liang » wang yang
liang yan » liang dan, liang tan, liang ying
yuan gain » run gain, yuan lin
yuan kai » yuan kang, yuan fei, tan kai
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi
hai » hadi, haji, hari

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 liang yan ((yuan gain) OR (yuan kai)) ((yang jui) OR (yang xi)) dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang yan ((yuan gain) or (yuan kai)) ((yang jui) OR (yang xi)) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang yan ((yuan gain) or (yuan kai)) ((yang jui) OR (yang xi)) dang hai ;*.
