Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trong » hanh trang, anh trong, hinh trong
hien xanh » hien hanh, hien nhanh, hien khanh
luong van » luong va, duong van, luong quan
luong vat » luong va, luong tai, dong vat
trong va » trong van, trong ca, trong cac
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 trong va thuong ((luong van) OR (luong vat)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (chieu xanh)) - hanh trong va thuong ((luong van) OR (luong vat)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (chieu xanh)) - hanh trong va thuong ((luong van) OR (luong vat)) toan ban*.
