Perhaps you should try some spelling variations:
yulu cheng » yu cheng, yuan cheng
yulu chen » yu chen
chan eng » chan fong, chan kang, chan ming
yu yang » du yang, yu fang, yu gang
yi yang » yin yang, yi gang, ying yang
chung h » chun h, chung _, chung hee
hung h » hung ho, hung _, hung n

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 ((yu yang) OR (yi yang)) ((yulu chen) OR (yulu cheng)) chan eng ((hung h) OR (chung h)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yu yang) or (yi yang)) ((yulu chen) or (yulu cheng)) chan eng ((hung h) OR (chung h)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yu yang) or (yi yang)) ((yulu chen) or (yulu cheng)) chan eng ((hung h) OR (chung h)) ;*.
