Perhaps you should try some spelling variations:
dang hadi » dang hai
qian yan » qian jun, qian yi
yuan kai » yuan kang, yuan fei, tan kai
yang jui » yang judy, yang di, yang yi
kang hay » eang hay, kang han, dang hai
yan yan » yan yuan, nan yan, yang yang
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: nan ((yan yan) OR (qian yan)) yuan kai ((yang jui) OR (yang xi)) ((kang hay) OR (dang hadi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan ((yan yan) OR (qian yan)) yuan kai ((yang jui) or (yang xi)) ((kang hay) or (dang hadi)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan ((yan yan) OR (qian yan)) yuan kai ((yang jui) or (yang xi)) ((kang hay) or (dang hadi)) ;*.
