Perhaps you should try some spelling variations:
hanh trang » thanh trung, canh tranh, minh trang
hanh trinh » canh tranh, hanh chinh
nhung cong » dung cong, thong cong, hang cong
doi trieu » dong trieu, doi chieu, doi trinh
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh lap, thanh cac

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: doi trieu tinh - ((hanh trang) OR (hanh trinh)) va nhung cong dan ((than cap) OR (phan tu))~.
• Adding a wildcard symbol may retrieve word variants: doi trieu tinh - ((hanh trang) or (hanh trinh)) va nhung cong dan ((than cap) or (phan tu))*.
