Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh chau » thanh cha, thanh cham, thanh chu
hanh mang » nhanh mang, hanh trang, nhanh lang
thanh cau » thanh mau, nhanh cau, thanh ca
ho chieu » theo chieu, hoc thieu, doi chieu
anh phan » hanh phan, anh nhan, anh han
va trong » va truong, va thong, va tuong
cong san » cong tac

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 mang) OR (anh phan)) va trong cong san ((thanh cau) OR (thanh chau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh mang) or (anh phan)) va trong cong san ((thanh cau) OR (thanh chau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh mang) or (anh phan)) va trong cong san ((thanh cau) OR (thanh chau))*.
