Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
manh trung » manh tung, manh hung, sinh trung
ho chieu » theo chieu, hoc thieu, doi chieu
cap dung » ap dung, cao dung, chan dung
dan dung » van dung, tin dung, ap dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

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) OR (manh trung)) ((cap dung) OR (dan dung)) cong dan than cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((thanh trung) or (manh trung)) ((cap dung) or (dan dung)) cong dan than cau*.
