Perhaps you should try some spelling variations:
cheng ping » chen ping, cheng bing, cheng ling
sin dann » sein dann, ein dank, sin cain
bin dann » sein dann, bin da, ein dank
yu cheng » yu chen, _ cheng
ping jin » ying jin, ping jia, ping lin
yang yue » wang yue, yang yun, yang yi
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi

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: done ((sin dann) OR (bin dann)) yu cheng ping jin ((yang yue) OR (((yang jui) OR (yang xi)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "done ((sin dann) or (bin dann)) yu cheng ping jin ((yang yue) or (((yang jui) OR (yang xi)))) ;~".
• Adding a wildcard symbol may retrieve word variants: done ((sin dann) or (bin dann)) yu cheng ping jin ((yang yue) or (((yang jui) OR (yang xi)))) ;*.
