Perhaps you should try some spelling variations:
yulu cheng » yulu chen, yu cheng, yuan cheng
cheng wang » chen wang, cheng zhang, chen yang
sin dann » sein dann, bin dann, ein dank
wang hui » wang hua, wang zhi, wang wei
yang yun » yang jun, tang yun, yang yue
wang yue » wong yue, wang hua, wang he
dong » doing, long, done
yang » ryang
yan » ryan

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: dong sin dann yulu cheng wang hui ((yang yun) OR (((wang yue) OR (wang yan)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong sin dann yulu cheng wang hui ((yang yun) or (((wang yue) OR (wang yan)))) ;~".
• Adding a wildcard symbol may retrieve word variants: dong sin dann yulu cheng wang hui ((yang yun) or (((wang yue) OR (wang yan)))) ;*.
