Perhaps you should try some spelling variations:
yulu cheng » yu cheng, yuan cheng
kang chung » kung chung, kang young, dang hung
yan liang » yang liang, wang liang, you liang
yulu chen » yu chen
chan kang » chung kang, chan eng, chan fong
yang li » yang lin, yang di, yang xi
hee » here, 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: ((yan liang) OR (yang li)) yang ((yulu chen) OR (yulu cheng)) chan kang chung hee ;~.
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang li)) yang ((yulu chen) or (yulu cheng)) chan kang chung hee ;*.
