Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
nhung cong » dung cong, thong cong, hang cong
hien xanh » hien hanh, hien nhanh, chieu xanh
trinh va » trinh van, trinh vat, trinh ve
cong dan » cong san, cong tan, huong dan
phap cau » pha cau, phap ca, phap cac
phan cau » phan dau, phan cac, phan tu

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh trinh va nhung cong dan ((phap cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - hanh trinh va nhung cong dan ((phap cau) OR (phan cau))*.
