Perhaps you should try some spelling variations:
yulu cheng » yu cheng, yuan cheng
yulu chen » yu chen
yin yang » ying yang, yin fang, yin hang
chan eng » chan fong, chan kang, chan ming
yi yang » yi gang, yu yang, ying yang
chung h » chung _, chung hee, chung chi
chun h » chun _, chun i, chun hui

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yin yang) OR (yi yang)) ((yulu chen) or (yulu cheng)) chan eng ((chun h) or (chung h)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yin yang) OR (yi yang)) ((yulu chen) OR (yulu cheng)) chan eng ((chun h) OR (chung h)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yin yang) OR (yi yang)) ((yulu chen) or (yulu cheng)) chan eng ((chun h) or (chung h)) ;*".
