Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh trinh » canh tranh, hanh chinh
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
toc lien » hoc lien, toc mien, tot lien
cong dan » cong san, cong tan, huong dan
toan cao » toan ban
toan tap » toan 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: toc lien quan - ((hanh mang) OR (hanh trinh)) cua nhung cong dan ((toan cao) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: toc lien quan - ((hanh mang) or (hanh trinh)) cua nhung cong dan ((toan cao) or (toan tap))*.
