Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
cua nhung » va nhung
hanh ban » thanh ban, hang ban, hanh san
cong dan » cong san, cong tan, huong dan
phan dau » phan tu, hang dau
ban cua » ban quan

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: "theo tieu xanh - hanh ban cua nhung cong dan ((phan lap) OR (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh ban cua nhung cong dan ((phan lap) OR (phan dau))*.
