Perhaps you should try some spelling variations:
chung kang » chan kang, chung kay, chung tong
yang yang » wang yang, wang yan
kang yong » kang young, wang yong, kong young
yong jui » yang jui, yang jun, yong cai
jui peng » jui meng, jee peng, hui ping
dean » dewan, jean, den
chew » che, chen, chee

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: wang ((yang yang) OR (yang dean)) chung kang yong jui peng chew ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yang yang) or (yang dean)) chung kang yong jui peng chew ;*.
