Perhaps you should try some spelling variations:
dan yang » daun yang, tan yang, wang yang
yu fang » yu wang, yu yang, yin fang
yu gang » xu gang, yi gang, yu wang
yan yan » yan yuan, yang yang, wang yan
yi yang » yin yang, yi gang, yu yang
nan yan » nan ya, wang yan, qian yan
n dan » _ dan, 1 dan, n das

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan ((yan yan) OR (nan yan)) n dan yang ((yi yang) or (((yu gang) or (yu fang)))) (hai or hadi) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan yan) OR (nan yan)) n dan yang ((yi yang) OR (((yu gang) OR (yu fang)))) (hai OR hadi) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan yan) OR (nan yan)) n dan yang ((yi yang) or (((yu gang) or (yu fang)))) (hai or hadi) ;*".
