Perhaps you should try some spelling variations:
hoc chieu » hoc thieu, hoc hien, hoc dieu
manh tung » manh hung, thanh tung
tung tuan » trung tuan, hung tuan, quang tuan
tuan dung » tuan duong, tran dung, tan dung
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tap

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) OR (ho chieu)) xanh - manh tung tuan dung ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (ho chieu)) xanh - manh tung tuan dung ((cong dan) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (ho chieu)) xanh - manh tung tuan dung ((cong dan) OR (cong tan)) toan cau*.
