Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh dang » hanh dong, hanh dung, hanh mang
cong manh » cong danh, duong manh, hoang manh
anh dang » anh dong, anh dung, anh bang
cua dang » cua cong, cua ban
toan cao » toan ban, toan tap

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: theo tieu xanh - ((hanh dang) OR (anh dang)) cua dang ((cong manh) OR (cong thanh)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - ((hanh dang) or (anh dang)) cua dang ((cong manh) OR (cong thanh)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh dang) or (anh dang)) cua dang ((cong manh) OR (cong thanh)) toan cao*.
