Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
van phuong » van phong, va phuong, van chuong
dong doanh » dung doanh, trong doanh, doanh doanh
chau tinh » cuu tinh, ha tinh, cua tinh
van duong » van dong, van dung, van phong
phan cau » phan dau, phan cac, phan lap
ho chau » ha chau, ho chu, o chau

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: ho chau tinh - hanh trinh ((van phuong) OR (van duong)) dong doanh ((phan cau) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chau tinh - hanh trinh ((van phuong) or (van duong)) dong doanh ((phan cau) OR (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - hanh trinh ((van phuong) or (van duong)) dong doanh ((phan cau) OR (phan tu))*.
