Perhaps you should try some spelling variations:
thue thanh » hue thanh, thu thanh, thuc thanh
thue xanh » thuc hanh, thuy anh, thu canh
hanh tang » hanh trang, anh tang, hanh mang
cong cong » cong dong, trong cong, dung cong
tang cua » mang cua, hang cua, tang luan
cong tan » cong tac, cong san, cong thanh
toan tai » toan tap, doanh tai, toan cao
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: cho ((thue xanh) OR (thue thanh)) - hanh tang cua cong cong tan ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((thue xanh) OR (thue thanh)) - hanh tang cua cong cong tan ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: cho ((thue xanh) OR (thue thanh)) - hanh tang cua cong cong tan ((toan tai) or (toan ban))*.
