Perhaps you should try some spelling variations:
yuhan chang » yuan chang, han chang, yuhuan huang
wang yuhan » wang luhang, wang yan, wang yidan
zhang ming » zhang xin
zhong tai » hong tan, zhong zhi
shang hai » shang kai, dang hai, chang ha
chang ii » change ii, zhang ii, change iii
hong hai » dang hai, hong tan, hong a
ii rene » iii rene, i rene, wie rene

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 yuhan chang ii rene zhang ming ((zhong tai) OR (((hong hai) OR (shang hai)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yuhan chang ii rene zhang ming ((zhong tai) or (((hong hai) OR (shang hai)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yuhan chang ii rene zhang ming ((zhong tai) or (((hong hai) OR (shang hai)))) ;*.
