Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
tieu xanh » tieu danh, chieu xanh, dieu hanh
cuong tap » luong tap, cong tac, luong tai
doanh cao » doanh co, doanh bao, doanh cho
trinh va » trinh van, trinh vat, trinh ve
va thong » va thuong, va phuong, he thong
cong tap » cong tac, cong tan, tong 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 va thong ((cong tap) OR (cuong tap)) doanh cao~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh trinh va thong ((cong tap) OR (cuong tap)) doanh cao*.
