Perhaps you should try some spelling variations:
chang hay » chang ha, change has, chang hee
gain yang » dan yang, daun yang, tan yang
chang mae » chang ha, changes made
yan clan » das clan, yan guan, yan yuan
clan yan » qian yan, nan yan
yan gain » fan again, you gain, run gain
yang yi » yang di, yang xi, yang jui
wang » wing, wan

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

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