Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
dang hadi » dang hai
lang yan » wang yan, zhang yan, lang lang
tan yang » dan yang, tan yong, tao yang
tan ying » fan ying, ran ying, tan yong
yi dang » yi gang, yi yang, yi chang

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((lang yan) OR (yang yang))) or (wang yang)) long run ((tan yang) or (tan ying)) yi dang hadi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((lang yan) OR (yang yang))) OR (wang yang)) long run ((tan yang) OR (tan ying)) yi dang hadi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((lang yan) OR (yang yang))) or (wang yang)) long run ((tan yang) or (tan ying)) yi dang hadi ;*".
