Perhaps you should try some spelling variations:
tinh thong » tinh thuong, trinh thong, tinh khong
tinh dung » trinh dung, tin dung, tinh quang
kien soat » kiem soat, bien soan, dien hoat
kien hoa » dien hoa, tien hoa, kien ha
quan van » quan va, quan luan, quan doan
van ke » van ket, van de, van ky
luan » lan
toan » tran

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 dung luan van ((kien soat) OR (kien hoa)) ) OR ( tinh thong quan van ke toan ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh dung luan van ((kien soat) OR (kien hoa)) ) or ( tinh thong quan van ke toan ))~".
• Adding a wildcard symbol may retrieve word variants: (( tinh dung luan van ((kien soat) OR (kien hoa)) ) or ( tinh thong quan van ke toan ))*.
