Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
canh trinh » canh tranh, canh tinh, anh trinh
hanh trinh » canh tranh, hanh chinh
toc chieu » toc thieu, doc hieu, hoc thieu
hang cong » dang cong, bang cong, thanh cong
hang nong » thang long, han tong
lang than » lang thang, lang thanh, sang 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: toc chieu xanh - ((canh trinh) OR (hanh trinh)) he ((hang cong) OR (hang nong)) lang than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc chieu xanh - ((canh trinh) or (hanh trinh)) he ((hang cong) OR (hang nong)) lang than cao~".
• Adding a wildcard symbol may retrieve word variants: toc chieu xanh - ((canh trinh) or (hanh trinh)) he ((hang cong) OR (hang nong)) lang than cao*.
