Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hang cong » dang cong, hang nong, bang cong
hanh san » thanh san, khach san, thanh son
cua hang » cua dang, cua nhung, cua cong
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban
san cua » sang cua, ban cua, dan cua

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: theo ((chuc nang) OR (chieu xanh)) - hanh san cua hang cong dan ((toan cau) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc nang) or (chieu xanh)) - hanh san cua hang cong dan ((toan cau) or (toan tap))*.
