working yue » working age, working out, working pur
hang when » change when, hands when
yan kong » tan kong, yan cong, yan kun

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 OR wing) OR lang) ((yan kong) OR (nan kong)) hang when change among working yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wing) or lang) ((yan kong) OR (nan kong)) hang when change among working yue ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wing) or lang) ((yan kong) OR (nan kong)) hang when change among working yue ;*.
