Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trung » thanh trung, hanh trang, manh trung
hien xanh » hien hanh, hien nhanh, hien khanh
dung cong » dung trong
trung ap » trung cap, trung lap, trung tam
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
toan ban » van ban
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: hoc ((hien xanh) OR (chieu xanh)) - hanh trung ap dung cong dan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (chieu xanh)) - hanh trung ap dung cong dan ((toan cau) or (toan ban))*.
