Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh hoan » trinh han, trinh hoa, trinh toan
hoan nhung » hoa nhung, hon nhung, doanh nhung
doan tien » doan thien, doanh tien, toan tien
cong dan » cong san, cong tan, cong dong
toan cau » 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: "doan tien thinh - hanh trinh hoan nhung ((cong dan) OR (huong dan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: doan tien thinh - hanh trinh hoan nhung ((cong dan) OR (huong dan)) toan cau*.
