Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, canh tranh, hanh trinh
hoc chieu » hoc thieu, ho chieu, hoc hien
thanh lap » thanh san, phan lap, thanh hai
thanh tay » thanh tai, thanh toan, thanh thuy
cua dung » cua dang, qua dung, cua rung
cua dong » chua dong, cua cong, cua dang
cong san » cong tac

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 chieu xanh - hanh trang ((cua dung) OR (cua dong)) cong san ((thanh lap) OR (thanh tay))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh trang ((cua dung) OR (cua dong)) cong san ((thanh lap) or (thanh tay))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hanh trang ((cua dung) OR (cua dong)) cong san ((thanh lap) or (thanh tay))*.
