Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
hien xanh » hien hanh, hien nhanh, chieu xanh
nhanh cau » thanh chau, nhanh ha, hang cau
nhanh cay » nhanh ha, nhanh bac, nhanh va
cua dung » cua dong, qua dung, cua rung
cua dang » cua cong, cua ban
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: hoc hien xanh - hanh trinh ((cua dung) OR (cua dang)) cong san ((nhanh cau) OR (nhanh cay))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh trinh ((cua dung) or (cua dang)) cong san ((nhanh cau) OR (nhanh cay))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - hanh trinh ((cua dung) or (cua dang)) cong san ((nhanh cau) OR (nhanh cay))*.
