Perhaps you should try some spelling variations:
wang qingqing » wang binglin, wang yangming, wang yongqin
wang danning » wang yanling, wang daoping, wang yangming
yang ying » yang yang, huang ying, liang ying
yang jing » wang jing, yang jin, huang jing
chang hai » chang ha, shang hai, change has
yuan hui » yuan fei, jaan hui, tuan hua
hui ying » huei ying, hoi ying, hui ping

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 qingqing)) yuan hui ying ((yang ying) OR (yang jing)) chang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang danning) or (wang qingqing)) yuan hui ying ((yang ying) OR (yang jing)) chang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang danning) or (wang qingqing)) yuan hui ying ((yang ying) OR (yang jing)) chang hai ;*.
