Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
tieu xanh » tieu danh, chieu xanh, dieu hanh
trinh van » trinh han, trinh quan, trinh toan
van thong » van thuong, van phong, va thong
cong tap » cuong tap, cong tan, tong tap
cong tac » cong ty
toan cao » toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - hanh trinh van thong ((cong tap) OR (cong tac)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh trinh van thong ((cong tap) OR (cong tac)) toan cao*.
