Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
manh tuong » manh tung, manh cuong, minh tuong
cat khong » vat khong, chat chong, chat phong
hanh toan » thanh toan, khanh toan, manh toan
ca khong » cua khong, va khong, ta khong
ban hanh » ban hang
toan ban » van ban

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: hoc ((thieu xanh) OR (chieu xanh)) - manh tuong ((ca khong) OR (cat khong)) ban hanh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - manh tuong ((ca khong) or (cat khong)) ban hanh toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - manh tuong ((ca khong) or (cat khong)) ban hanh toan ban*.
