Perhaps you should try some spelling variations:
cheng ying » cheng bing, cheng ling, cheng ming
sein dann » sein kann, sein das, bin dann
yu cheng » yu chen, _ cheng
ying jin » yang jin, jing ji, yang jie
wong yue » wang yue, hong yu
dann yu » wann yu
lang di » yang di, wang di, klang die

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 yu cheng ying jin ((((wang yan) OR (wong yue))) OR (lang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: (dong or doing) sein dann yu cheng ying jin ((((wang yan) or (wong yue))) or (lang di)) ;*.
