Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tran » thanh trang, thanh toan, thanh tuan
hien xanh » hien hanh, hien nhanh, hien khanh
thanh tra » thanh toan, thanh hoa
dung cong » dung trong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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) OR (chieu xanh)) - ((thanh tran) OR (thanh tra)) tin dung cong dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (chieu xanh)) - ((thanh tran) or (thanh tra)) tin dung cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (chieu xanh)) - ((thanh tran) or (thanh tra)) tin dung cong dan than cao*.
