Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
nhan dang » nhan dan, phan dang, tran dang
va trong » va truong, va thong, va tuong
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan tap
dang va » dang van, dang vat, hang va

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 - nhan dang va trong cong dan ((toan cau) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - nhan dang va trong cong dan ((toan cau) or (toan cao))*.
