Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, canh tranh, hanh trinh
mat duong » mai duong, xuat duong, hai duong
ho chieu » theo chieu, hoc thieu, doi chieu
van dung » van dong, xay dung, tin dung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap
va dung » va duong, vat dung, va ung

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 xanh - hanh trang ((((va dung) OR (van dung))) or (mat duong)) cong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trang ((((va dung) OR (van dung))) OR (mat duong)) cong dan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trang ((((va dung) OR (van dung))) or (mat duong)) cong dan toan cao*".
