Perhaps you should try some spelling variations:
thing adding » phone adding, thing hiring
when adding » why adding, when handling, when adapting
wang dan » wang yan, wang ban, wang yidan
dan ying » dan qing, dan yang, fan ying
ii first » i first, 2 first, 3 first
ai first » i first, mali first, 2 first
dong bin » dong sin, dong di, dann bin

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 dan ying ((ii first) OR (ai first)) ((thing adding) OR (when adding)) dong bin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan ying ((ii first) or (ai first)) ((thing adding) OR (when adding)) dong bin ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan ying ((ii first) or (ai first)) ((thing adding) OR (when adding)) dong bin ;*.
