Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
liang sun » liang dan, liang tan, wing sun
chang han » chang ha, cheng han, zhang han
han myung » han kyung, han heung
myung won » kyung woo, myung koo, seung won
yan yuan » yan guan, fang yuan, nan yan
dong di » dong sin
won siu » wong siu, wong shiu, 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: ((liang sun) OR (dong di)) ((yang liang) OR (yan yuan)) chang han myung won siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((liang sun) or (dong di)) ((yang liang) or (yan yuan)) chang han myung won siu ;*.
