Perhaps you should try some spelling variations:
change has » change hands, change heat, change how
yi change » i change, yi chang, ii changes
gain yang » dan yang, daun yang, tan yang
lang yan » wang yan, wang yang, zhang yan
yan jing » yang jing, wang jing, bian jing
tan yong » tan kong, tan yang, tan ying
jing ji » ying jin

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 jing ji ((gain yang) or (((tan yong) OR (tan hong)))) yi change has ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan jing ji ((gain yang) OR (((tan yong) OR (tan hong)))) yi change has ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan jing ji ((gain yang) or (((tan yong) OR (tan hong)))) yi change has ;".
• Adding a wildcard symbol may retrieve word variants: lang yan jing ji ((gain yang) or (((tan yong) OR (tan hong)))) yi change has ;*.
