The purpose of a laptop

A pamphlet used to record all kinds of things. When man did not invent writing, he often used knotting to record numbers or events, to express certain meanings and to convey information. 

It can be seen from the objects of the primitive society, such as the net pattern, the rope pattern on the pottery and the pottery net pendant, that the counting of knots is one of the recording methods widely used by the primitive ancestors. NOTEPAD can not only record the time, as the ancient people (originally meant to knot knot records) , but also can spread culture, because of life and gradually rough heart.
