Perhaps you should try some spelling variations:
cua khong » cua phuong, cua thuong, cua cong
hua khong » hoa khong, hoac khong, phuc khong
cua tinh » cua sinh, ha tinh, hoa tinh
anh tang » anh bang, anh dang, anh nang
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan tap » toan ban
va tinh » may tinh

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: theo ((cua tinh) OR (va tinh)) - anh tang ((cua khong) OR (hua khong)) cong dan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((cua tinh) OR (va tinh)) - anh tang ((cua khong) or (hua khong)) cong dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((cua tinh) OR (va tinh)) - anh tang ((cua khong) or (hua khong)) cong dan toan tap*.
