Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
cong van » congo can, duong van
cong sun » cong shu, wing sun
gan guan » yan guan, quan guan, fan guon
song man » song min, young man, song ming
kann von » kann man, kann ein, bonn von
dong di » dong sin
von siu » von seu, von sinn, kong siu

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: ((((cong van) OR (cong sun))) OR (dong di)) ((yang liang) OR (gan guan)) song man kann von siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((cong van) or (cong sun))) or (dong di)) ((yang liang) or (gan guan)) song man kann von siu ;*.
