Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
manh tran » manh tuan, canh tranh, hanh trang
manh toan » thanh toan, anh tuan, tinh toan
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, xuan toan
toan cao » toan ban, toan tap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (toc thieu)) xanh - ((manh tran) OR (manh toan)) thanh dung cong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (toc thieu)) xanh - ((manh tran) OR (manh toan)) thanh dung cong dan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (toc thieu)) xanh - ((manh tran) OR (manh toan)) thanh dung cong dan toan cao*".
