Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san, tinh toan
nhung cong » dung cong, thong cong, hang cong
thanh tra » thanh hoa
van nhung » van nhuong, va nhung, van hung
chi xanh » chi anh, chi danh, chi hanh
cong anh » cong danh, dong anh, hong anh
tuan cau » toan cau, quan cau, thuan cam
doi chi » doi khi
tuan cu » tuan tu, quan cua, tuan thu

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