Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh toan » thanh hoa, thanh san, tinh toan
hoc thieu » toc thieu, hoc hien
hanh hinh » hanh chinh, hanh tinh, hanh dinh
dong cong » duong cong, dung cong, dang cong
hinh cua » chinh cua, sinh cua, tinh cua
cua dong » chua dong, cua cong, cua dang
dan toan » van toan, dan than, manh toan

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 hinh cua dong cong ((dan toan) OR (thanh toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh hinh cua dong cong ((dan toan) or (thanh toan)) cau*.
