The Four Treasures of the Scholar's House is ink.

The ink is known as the gold is not changed from the ink scripture: "Where the ink is used day by day, a year before the reduction of half a penny, such as ten thousand gold is not exchanged." Therefore, Jin Bu Ruai became the name of the ink, meaning that a good ink is not exchangeable for thousands of gold.

Prehistoric colored pottery decorations, Shang and Zhou oracle bone inscriptions, bamboo and wooden documents, thick silk calligraphy and painting, etc. everywhere left the traces of the original use of ink. According to the literature, ink was also used in the ancient ink torture (face tattooing), ink rope (used in carpentry), and ink turtle (divination). Chinese archaeological excavations of the 14th century B.C. bone and stone tools have been inked, but also from Hubei Yunmeng County excavated from the Warring States period of the ink block.

The impression of ink seems to be a little too single, but it was an indispensable item in ancient writing. With the help of this original material, the fantastic and wonderful artistic mood of Chinese calligraphy and painting can be realized. The world of ink is not boring, but rich. As a consumable product, ink is precious when it can be presented intact as it is today.
