Perhaps you should try some spelling variations:
huang xiaoting » wang xiaoping
lang xiaotong » wang xiaodong, wang xianodong, zhang xiaoyong
zhang hua » zhang hui, zhang shuo, wang hua
hong than » hong tan, long thanh
ran ying » fan ying, tan ying, jin ying
ying jin » yang jin, jing ji, yang jie
hong hai » shang hai, zhong tai, dang hai
hua ran » hua ban, hua ren

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: ((lang xiaotong) OR (huang xiaoting)) zhang hua ran ying jin ((hong than) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang xiaotong) OR (huang xiaoting)) zhang hua ran ying jin ((hong than) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang xiaotong) OR (huang xiaoting)) zhang hua ran ying jin ((hong than) or (hong hai)) ;*.
