Perhaps you should try some spelling variations:
wang qingqing » wang binglin, wang yangming, wang yongqin
wang danning » wang yanling, wang daoping, wang yangming
huang ying » huang jing, huang ting, huang yang
yang ying » yang yang, yang jing, liang ying
chang hai » chang ha, shang hai, change has
tuan hua » tan hua, tuan vu, yuan hui
hua yang » hui yang, huang yang, hua jiang

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