Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
ho chieu » theo chieu, hoc thieu, doi chieu
le trong » le trung, ly trong, le tang
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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 - ((canh tranh) OR (thanh trung)) le trong cong tan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((canh tranh) or (thanh trung)) le trong cong tan ((toan cau) or (toan ban))*.
