Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
doanh luan » doanh nhan
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
cong tac » cong ty
tac chay » tac cay, tac chuan, toan chay
chay tu » chay tui, chai tu, chay dua

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - lanh ((doanh cua) OR (doanh luan)) dung cong tac chay tu~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - lanh ((doanh cua) OR (doanh luan)) dung cong tac chay tu*.
