Perhaps you should try some spelling variations:
thanh tung » thanh cong
trong san » trong cac, cong san, dong san
cac dieu » cau dieu, cac bieu, cac diem
cac kieu » cach tieu, cac yeu, tac kiem
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban
tung va » trung va, tuong va, dung va
va dung » van dung, va duong, vat dung

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: ((cac dieu) OR (cac kieu)) tinh - thanh tung va dung trong san ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((cac dieu) OR (cac kieu)) tinh - thanh tung va dung trong san ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((cac dieu) OR (cac kieu)) tinh - thanh tung va dung trong san ((toan tai) or (toan ban))*.
