Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
manh trung » manh tung, thanh trung, manh hung
tran thong » tran hong, tran trong, tran phong
ho chieu » theo chieu, hoc thieu, doi chieu
cong san » cong tac
san tuan » van tuan, san luan, san quan
tuan ban » tuan bang, toan ban, luan 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 sang - manh trung ((toan thong) OR (tran thong)) cong san tuan ban~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - manh trung ((toan thong) or (tran thong)) cong san tuan ban*.
