Perhaps you should try some spelling variations:
wang liang » wang yang
liang dan » liang tan, king dan, liang sun
zhang xin » zhang jian, zhang fan, zhang yan
chan ming » kian ming, chan eng, chan fong
zhang zhi » zhong zhi, wang zhi, zhang wei
yan sher » khan sher, can she, han shen
dan yan » dan yang, nan yan, wang yan

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 liang dan yan sher ((((zhang ming) OR (zhang xin))) OR (chan ming)) zhang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang dan yan sher ((((zhang ming) OR (zhang xin))) or (chan ming)) zhang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang dan yan sher ((((zhang ming) OR (zhang xin))) or (chan ming)) zhang zhi ;*.
