Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh cac » hanh cac, thanh ca, tranh cac
thanh bac » nhanh bac, thanh bai, thanh san
ho chieu » theo chieu, hoc thieu, doi chieu
dan dung » van dung, tin dung
cong dan » cong san, cong tan, huong dan
ap dung » xay dung, van dung

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: ho chieu xanh - thanh trung ((dan dung) OR (ap dung)) cong dan ((thanh cac) OR (thanh bac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trung ((dan dung) or (ap dung)) cong dan ((thanh cac) OR (thanh bac))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trung ((dan dung) or (ap dung)) cong dan ((thanh cac) OR (thanh bac))*.
