Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trinh » canh tranh, hanh chinh
huong manh » duong manh, hung manh, phuong danh
luong manh » duong manh, luong thanh, duong minh
hien xanh » hien hanh, hien nhanh, hien khanh
trinh va » trinh van, trinh vat, trinh ve
toan ban » van ban

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)) - hanh trinh va nhung ((huong manh) OR (luong manh)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (chieu xanh)) - hanh trinh va nhung ((huong manh) or (luong manh)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (chieu xanh)) - hanh trinh va nhung ((huong manh) or (luong manh)) toan ban*.
