Perhaps you should try some spelling variations:
wang danning » wang yangming, wang ning
wang daoping » wang xiaoping, wang xiaobing, wang leiping
hua irene » hua ren
yang hua » wang hua, yang hui, ying hua
phan thi » pham thi, nhan thi, tran thi
thi hong » tan hong
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: ((((wang danning) OR (wang daoping))) OR (wang yanling)) yang hua irene phan thi hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang danning) OR (wang daoping))) or (wang yanling)) yang hua irene phan thi hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang danning) OR (wang daoping))) or (wang yanling)) yang hua irene phan thi hong yu ;*.
