Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
cap duong » cau duong, cac duong, cap dung
ho chieu » theo chieu, hoc thieu, doi chieu
van dung » van dong, xay dung, tin dung
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan ban » van ban
ap dung » xay 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 ((cap duong) OR (((ap dung) OR (van dung)))) cong san toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trung ((cap duong) or (((ap dung) OR (van dung)))) cong san toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trung ((cap duong) or (((ap dung) OR (van dung)))) cong san toan ban*.
