Perhaps you should try some spelling variations:
yulu cheng » yulu chen, yu cheng, yuan cheng
cheng ming » cheng bing, cheng ling, chen ping
sein dann » sein kann, sein das, bin dann
ming jin » ying jin, min jin, ming qing
wang yue » wang hua, wang yan, wang he
wong yue » hong yu
yang jui » yang judy, yang di, yang xi

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 OR doing) sein dann yulu cheng ming jin ((((wang yue) OR (wong yue))) OR (yang jui)) ;~.
• Adding a wildcard symbol may retrieve word variants: (dong or doing) sein dann yulu cheng ming jin ((((wang yue) or (wong yue))) or (yang jui)) ;*.
