Perhaps you should try some spelling variations:
theo chau » theo chu, theo chieu, theo phap
chau tinh » cuu tinh, ha tinh, cua tinh
hanh mang » nhanh mang, hanh trang, nhanh lang
cua tong » cua cong, cua nong, cua song
cua dong » chua dong, cua cong, cua dang
cong tac » cong ty
toan cao » toan ban
toan tap » toan 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: theo chau tinh - hanh mang ((cua tong) OR (cua dong)) cong tac ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chau tinh - hanh mang ((cua tong) or (cua dong)) cong tac ((toan cao) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo chau tinh - hanh mang ((cua tong) or (cua dong)) cong tac ((toan cao) OR (toan tap))*.
