Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan dana » dan dana, fidan ana
gain yang » dan yang, daun yang, tan yang
yi chang » ii chang, ying chang, jin chang
yi gang » i gang, li gang, yi yang
dana n » dana _, dana b, dana k
n gain » _ gain, run gain

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

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