Perhaps you should try some spelling variations:
chung kang » chan kang, chung kay, chung tong
yang yang » wang yang, wang yan
kang tong » kang young
yang yao » wang yan, yang fan
yu cheng » yu chen, _ cheng
tong hui » wang hui
yang yi » yang di, yang xi, yang jui
n chen » _ chen, a chen, z chen

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yang yao) or (yang yang))) or (yang yi)) ((n chen) or (yu cheng)) chung kang tong hui ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang yao) OR (yang yang))) OR (yang yi)) ((n chen) OR (yu cheng)) chung kang tong hui ;.
• Adding a wildcard symbol may retrieve word variants: wang ((((yang yao) or (yang yang))) or (yang yi)) ((n chen) or (yu cheng)) chung kang tong hui ;*.
