Perhaps you should try some spelling variations:
thuat tinh » thuat trinh, thuat kinh, thuat hinh
chua tinh » cua tinh, cha tinh, cuu tinh
luan dung » lan dung, luan dong, luan hung
trong tac » trong cac, tuong tac, trong tan
anh dung » anh dong, anh huong, sach dung
tac toan » tap toan, tam toan, hach toan
toan ban » van ban
benh » binh

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: ho ((((chua tinh) OR (chua benh))) OR (thuat tinh)) - anh dung luan dung trong tac toan ban~.
• Adding a wildcard symbol may retrieve word variants: ho ((((chua tinh) or (chua benh))) or (thuat tinh)) - anh dung luan dung trong tac toan ban*.
