Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
hanh trang » thanh trung, canh tranh, hanh trinh
chi xanh » chi anh, chi danh, chi hanh
va trong » va truong, va thong, va tuong
cong ban » cong bang, cong san, cong tan
ban hang » ngan hang
hang tai » hang va, dung tai
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 xanh - ((thanh tran) OR (hanh trang)) va trong cong ban hang tai~.
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - ((thanh tran) or (hanh trang)) va trong cong ban hang tai*.
