Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
manh toan » thanh toan, tinh toan
ho chieu » theo chieu, hoc thieu, doi chieu
tinh cua » trinh cua, sinh cua, tinh chat
ban cong » bang cong, van cong, phan cong
dan toan » van toan, dan than, xuan toan

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 - hanh tinh cua ban cong ((dan toan) OR (((manh toan) OR (anh tuan)))) cao~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh tinh cua ban cong ((dan toan) or (((manh toan) or (anh tuan)))) cao*.
