Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh toan » thanh hoa, thanh san, tinh toan
luong van » luong va, duong van, luong vat
van thanh » ban thanh, van tuan
thanh cau » thanh chau, thanh mau, nhanh cau
va lang » hoa lang
va nang » van nang, da nang, cam nang

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)) - thanh toan ((va lang) OR (va nang)) luong van thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (chieu xanh)) - thanh toan ((va lang) OR (va nang)) luong van thanh cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (chieu xanh)) - thanh toan ((va lang) OR (va nang)) luong van thanh cau*.
