Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hanh trinh » canh tranh
hoc thieu » toc thieu, hoc hien
va phuong » cac phuong
cong danh » cuong danh, cong dan, cong thanh
danh tuan » anh tuan, manh tuan, danh thanh
tuan chau » tran chau, chuan chau, thanh chau

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 trinh) OR (hanh chinh)) ((va thuong) OR (va phuong)) cong danh tuan chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh trinh) OR (hanh chinh)) ((va thuong) or (va phuong)) cong danh tuan chau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh trinh) OR (hanh chinh)) ((va thuong) or (va phuong)) cong danh tuan chau*.
