Perhaps you should try some spelling variations:
when adding » why adding, when handling, when adapting
adding dann » adding latin
wang fan » wang yan, yang fan, wang ban
fan ying » fan xing, ran ying, tan ying
ii first » 2 first, 3 first, 1 first
ai first » mali first, 2 first, 3 first
dann bin » dong bin
i first » 2 first, 3 first, 1 first

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 fan ying ((ii first) OR (((ai first) OR (i first)))) when adding dann bin ;~.
• Adding a wildcard symbol may retrieve word variants: wang fan ying ((ii first) or (((ai first) or (i first)))) when adding dann bin ;*.
