Perhaps you should try some spelling variations:
when adding » why adding, when handling, when adapting
first when » first what, first week, first win
yan yang » yang yang, dan yang, tan yang
tan ying » fan ying, ran ying, tan yang
yao yang » yang yang
i first » ai first, ii first, 2 first
dong » doing, long, done
sin » sign, sind, skin

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: lang ((((yan yang) OR (tan ying))) OR (yao yang)) i first when adding dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((yan yang) or (tan ying))) or (yao yang)) i first when adding dong sin ;*.
