Yes, handwriting has been associated with human culture. In order to have a "smile on white paper" handwriting, we cannot help but mention the pen, which has been associated with human civilization. In Confucian times, Asian pens made of rabbit hair attached to bamboo, ink was a solid that was grinded for hours to become liquid. When Confucianism ended, giving way to Western learning, our country appeared pencil and ink. Pencil made of wood has a long tube cut in it. In the middle of that tube is a lead. Lead is a soft wood that has been burned. When written it emits a smooth black color. Over time, lead was made chemically, in state-of-the-art factories. The blackness of lead is specified by the numbers 1B to 4B, 5B, and so on. The pencil consists of two main parts, the pencil case and the lead core. The inner lead core is mixed from lead and clay, then dipped in wax and poured into half of the pen case with small grooves, then the other half of the pen shell will be placed on to cover the inner core. Outside, the manufacturer often paints it with enough colors to protect the pencil case as well as make it more beautiful. Just looking at the simple structure, but how great its use is, everyone knows, if there is no pencil, how can we learn and write the first letters. Pencils are forever a beautiful memory of each of us.
