Perhaps you should try some spelling variations:
wang xiaotong » wang xiaodong, wang xianodong, wang xiaoping
zhang hua » zhang hui, zhang shuo, wang hua
ran yang » tan yang, wang yang, yang yang
ran ying » fan ying, tan ying, jin ying
dan yang » daun yang, tan yang, wang yang
jie hong » jie song, xie hong, jie zhang
tan » than

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 xiaotong zhang hua ((((ran yang) OR (ran ying))) OR (dan yang)) jie hong tan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xiaotong zhang hua ((((ran yang) OR (ran ying))) or (dan yang)) jie hong tan ;~".
• Adding a wildcard symbol may retrieve word variants: wang xiaotong zhang hua ((((ran yang) OR (ran ying))) or (dan yang)) jie hong tan ;*.
