Perhaps you should try some spelling variations:
doanh luan » doanh nhan
tranh cua » doanh cua, manh cua
trong van » trong cac
van thanh » ban thanh, van tuan
thanh tap » thanh lap, thanh tai, thanh tay
chi xanh » chi anh, chi danh, chieu xanh
chi hanh » chi nhanh, chi thanh, thi hanh

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) OR (chi hanh)) - canh ((tranh cua) OR (doanh luan)) dung trong van thanh tap~.
• Adding a wildcard symbol may retrieve word variants: doi ((chi xanh) or (chi hanh)) - canh ((tranh cua) or (doanh luan)) dung trong van thanh tap*.
