Perhaps you should try some spelling variations:
thuong cong » thong cong, thuong con, thuong dong
hanh trinh » canh tranh, hanh chinh
cua thuong » cua truong, cua phuong, ca thuong
trinh cua » tinh cua, trinh luat, trinh quan
cap chon » cap cho, tap chon, tap cho
chon van » chon va, thong van, phong van
dan toan » van toan, manh toan, xuan toan
dan than » dan chan, ban than, van than

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: cap chon van - hanh trinh cua thuong cong ((dan toan) OR (dan than)) cao~.
• Adding a wildcard symbol may retrieve word variants: cap chon van - hanh trinh cua thuong cong ((dan toan) or (dan than)) cao*.
