Perhaps you should try some spelling variations:
qian sheng » qin zheng, fujian sheng
wang yang » wang yan, wang liang, wang yanling
qin cheng » qin zheng, hin cheung, qin china
fan duong » fan along, fan guon, lam duong
duong van » cong van, duong anh
yang xi » yang di, yang yi, yang jui
han fan » zhang fan, zhai fan, yang fan

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: (wing OR lang) ((wang yang) OR (yang xi)) ((qin cheng) OR (qian sheng)) han fan duong van ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wing or lang) ((wang yang) or (yang xi)) ((qin cheng) OR (qian sheng)) han fan duong van ;~".
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((wang yang) or (yang xi)) ((qin cheng) OR (qian sheng)) han fan duong van ;*.
