Perhaps you should try some spelling variations:
thien thanh » tien thanh, thi thanh, hien hanh
thieu xanh » chieu xanh, hieu manh, thien anh
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
tuong van » truong van, duong van, thong van
trong van » trong cac
tinh cua » trinh cua, sinh cua, tinh chat
cua tong » cua cong, cua dong, cua nong
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 ((thieu xanh) OR (thien thanh)) - hanh tinh cua tong ((tuong van) OR (trong van)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (thien thanh)) - hanh tinh cua tong ((tuong van) OR (trong van)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (thien thanh)) - hanh tinh cua tong ((tuong van) OR (trong van)) toan ban*.
