Perhaps you should try some spelling variations:
hanh trinh » hanh chinh
quan hanh » quan thanh, quang thanh, quang khanh
hanh cong » thanh cong, hang cong, hanh dong
cong manh » cong danh, duong manh, cong thanh
chat hoa » thuat hoa, chat va, chat huu
hoa danh » hoa doanh, hoa dan, hop danh
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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: chat hoa danh - ((hanh trinh) OR (canh tranh)) quan hanh cong manh ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chat hoa danh - ((hanh trinh) or (canh tranh)) quan hanh cong manh ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: chat hoa danh - ((hanh trinh) or (canh tranh)) quan hanh cong manh ((toan cau) OR (toan ban))*.
