Perhaps you should try some spelling variations:
thanh tra » thanh toan, thanh hoa
va phuong » va thuong, cac phuong
chi hanh » chi nhanh, chi thanh, thi hanh
va thong » va thuong, he thong, va cong
cong anh » cong danh, dong anh, hong anh
tuan cau » toan cau, quan cau, tuan cu
doi chi » doi khi

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: doi chi hanh - ((thanh tra) OR (tinh toan)) ((va thong) OR (va phuong)) cong anh tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi hanh - ((thanh tra) or (tinh toan)) ((va thong) OR (va phuong)) cong anh tuan cau~".
• Adding a wildcard symbol may retrieve word variants: doi chi hanh - ((thanh tra) or (tinh toan)) ((va thong) OR (va phuong)) cong anh tuan cau*.
