Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
tieu xanh » tieu danh, dieu hanh, tien anh
van thanh » ban thanh, van tuan
thanh ban » thanh san, thanh van, thanh bac
cong van » cong vang, cong san, song van
va hanh » van hanh, va thanh, va danh

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: theo ((tieu xanh) OR (chieu xanh)) - thanh tung ((va hanh) OR (van dong)) cong van thanh ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) OR (chieu xanh)) - thanh tung ((va hanh) or (van dong)) cong van thanh ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) OR (chieu xanh)) - thanh tung ((va hanh) or (van dong)) cong van thanh ban*.
