Perhaps you should try some spelling variations:
cheng tong » chung tong, cheng leong, chen rong
yan liang » yang liang, wang liang, you liang
yang yang » wang yang, wang yan
tong king » ton kino, tong song
duong van » cong van, duong anh
kong van » cong van, kong hang, kong land
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 tong king ((kong van) OR (duong van)) ;~.
• Adding a wildcard symbol may retrieve word variants: qian ((yan liang) or (yang yang)) a cheng tong king ((kong van) or (duong van)) ;*.
