Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
trong dan » trong dang, trong san, trong ban
trong tan » trong quan, trong cac, trong ca
ho chieu » theo chieu, hoc thieu, doi chieu
van dung » van dong, xay dung, tin dung
toan cau » toan cao, toan ban, toan tap
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 ((ap dung) OR (van dung)) ((trong dan) OR (trong tan)) toan cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trung ((ap dung) or (van dung)) ((trong dan) or (trong tan)) toan cau*.
