Who invented writing?

In the Yellow Emperor, a person in charge of writing records drew some symbols on the ground for the convenience of remembering things. This is the earliest writing. It is said that this man is called Cang Jian.

Characters can be divided into: pictographic characters and contractual characters. The inscriptions of Oracle Bone Inscriptions and Zhong Dingwen belong to hieroglyphics, and the present style of regular script in Song Dynasty belongs to cuneiform.

We call books books rather than keyboards, which was decided by our ancestors. You should ask them.
