Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
yang yang » wang yang, wang yan
cheng ton » cheng boon, chung tong, cheng han
king kong » hong kong
ton king » tong king, ton kino, john king
kong van » cong van, duong van, kong hang
a cheng » _ cheng, a chen, tan cheng

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: qian ((yan liang) OR (yang yang)) a cheng ton king kong van ;~.
• Adding a wildcard symbol may retrieve word variants: qian ((yan liang) or (yang yang)) a cheng ton king kong van ;*.
