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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: doi ((chi xanh) OR (chi hanh)) - canh ((tranh cua) or (doanh luan)) dung trong van toan tap~.
• 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 toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) OR (chi hanh)) - canh ((tranh cua) or (doanh luan)) dung trong van toan tap*".
