Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hanh tranh » canh tranh, hanh trinh, hanh trang
nhung cong » dung cong, thong cong, nhung don
hoc thieu » toc thieu, hoc hien
tranh cua » doanh cua, manh cua
hang cong » dang cong, hang nong, bang cong
dan can » dan chan, dan canh, dan ca
can cau » van cau, ban cau, ca cau

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 - hanh tranh cua ((nhung cong) OR (hang cong)) dan can cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh tranh cua ((nhung cong) or (hang cong)) dan can cau*.
