Perhaps you should try some spelling variations:
zhong zhi » zhang zhi, hong ghi, zhong tai
sun jian » sun japan, sun qiang, sun yan
vun jian » jun jean, wen jian, wu jian
yang jie » yang jin, yang di, yang jui
hong hai » shang hai, zhong tai, dang hai
yan han » man han, yan zhang, kang han
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 yan han ((sun jian) OR (vun jian)) yang jie ((hong hai) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan han ((sun jian) OR (vun jian)) yang jie ((hong hai) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan han ((sun jian) OR (vun jian)) yang jie ((hong hai) or (zhong zhi)) ;*.
