Perhaps you should try some spelling variations:
thing hiring » things sharing, things during, thing adding
wang dan » wang yan, wang yidan, wang yang
wang ban » wang yan, wang yang, bang bang
ii first » i first, 2 first, 3 first
ai first » i first, mali first, 2 first
dong » doing, long, done
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang dan) OR (wang ban)) yang ((ii first) or (ai first)) thing hiring dong sin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dan) OR (wang ban)) yang ((ii first) OR (ai first)) thing hiring dong sin ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) OR (wang ban)) yang ((ii first) or (ai first)) thing hiring dong sin ;".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) OR (wang ban)) yang ((ii first) or (ai first)) thing hiring dong sin ;*.
