Perhaps you should try some spelling variations:
huong luan » huong lan, cuong luan, huong loan
kiem soat » kiem toan
ban hanh » ban hang
van tien » toan tien, van hieu, van tuan
tien hoa » dien hoa, trien hoat, tien va
ban dan » ban hang, ban quan, gian dan
tinh » trinh, dinh, minh

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: (( tinh quang ((ban dan) OR (ban hanh)) kiem soat ) OR ( anh huong luan van tien hoa ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh quang ((ban dan) OR (ban hanh)) kiem soat ) or ( anh huong luan van tien hoa ))~".
• Adding a wildcard symbol may retrieve word variants: (( tinh quang ((ban dan) OR (ban hanh)) kiem soat ) or ( anh huong luan van tien hoa ))*.
