Perhaps you should try some spelling variations:
thanh trung » thanh tung
mot chieu » doi chieu
ho chieu » theo chieu, hoc thieu, doi chieu
tan dung » tran dung, tin dung, dan dung
van dung » van dong, xay dung, tin dung
cong van » cong vang, cong san, song van
van tuan » van quan, van ban, anh tuan
tuan tai » toan tai, quan tai, tan tai

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