Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trinh » canh tranh, hanh chinh
hien xanh » hien hanh, hien nhanh, hien khanh
trinh cua » tinh cua, trinh luat, trinh quan
cua nhung » va nhung
duong van » luong va, dang van, trong van
duong va » dung va, luong va, dong va
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 cua nhung ((duong van) OR (duong va)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (chieu xanh)) - hanh trinh cua nhung ((duong van) OR (duong va)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (chieu xanh)) - hanh trinh cua nhung ((duong van) OR (duong va)) toan ban*.
