Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh hua » trinh hoa, trinh cua, trinh ha
hua khong » hoa khong, cua khong, hoac khong
khi xanh » khia canh, thi hanh, thi anh
cong san » cong tac
toan cau » toan ban, toan tap, toan tai
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: "doi khi xanh - hanh trinh hua khong ((cong san) OR (cong ty)) ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - hanh trinh hua khong ((cong san) OR (cong ty)) ((toan cau) OR (toan cao))*.
