Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh mang » nhanh mang, hanh trang, nhanh lang
nhan dang » nhan dan, phan dang, tran dang
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » 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 mang) OR (nhan dang)) cua nhung cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh mang) or (nhan dang)) cua nhung cong dan toan cau*.
