Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trinh » canh tranh, hanh chinh
luat hang » luat hanh, luat chung, luat quang
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
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: ho ((chieu xanh) OR (chieu tinh)) - hanh trinh luat hang ((cong tan) OR (cong tac)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - hanh trinh luat hang ((cong tan) OR (cong tac)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - hanh trinh luat hang ((cong tan) OR (cong tac)) toan cao*.
