Perhaps you should try some spelling variations:
xiaodong chang » xiaotong zhang
xiaodong huang » xiaotong zhang
zhang hari » zhang dai, shang hai, zhang han
pei yang » wei yang, hui yang, pei yun
li zhang » _ zhang
e yang » _ yang, h yang, wei yang
wang » wing, wan, lang

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 ((xiaodong chang) OR (xiaodong huang)) chen ((e yang) OR (pei yang)) li zhang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((xiaodong chang) OR (xiaodong huang)) chen ((e yang) or (pei yang)) li zhang hari ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((xiaodong chang) OR (xiaodong huang)) chen ((e yang) or (pei yang)) li zhang hari ;*.
