yang using » yang jing, making using, change using
gain yang » dan yang, daun yang, tan yang
cheng hei » chen wei, cheng han, zheng he
run gain » run pain
chen lei » chen wei, chen e, chen l
hat » what, heat

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

• Performing a fuzzy search may retrieve terms with similar spellings: wing ((can change) or (man hat)) run gain yang using ((cheng hei) OR (chen lei)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((can change) OR (man hat)) run gain yang using ((cheng hei) OR (chen lei)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((can change) or (man hat)) run gain yang using ((cheng hei) OR (chen lei)) ;*".
