Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tran » thanh trang, thanh toan, thanh tuan
duong cong » dung cong, luong cong, duong trong
hoc thieu » toc thieu, hoc hien
thanh tra » thanh toan, thanh hoa
van duong » van dong, van dung, van phong
khanh cap » hanh cap, hanh cac, hanh cat
cong dan » cong san, cong tan, huong dan
khan cap » khan ap, than cap, khoan cam

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 thieu xanh - ((thanh tran) OR (thanh tra)) van duong cong dan ((khanh cap) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((thanh tran) or (thanh tra)) van duong cong dan ((khanh cap) OR (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((thanh tran) or (thanh tra)) van duong cong dan ((khanh cap) OR (khan cap))*.
