The inkstone is introduced as follows:

Inkstone, also known as inkstone, is one of the traditional Chinese handicrafts. Inkstone, together with pen, ink and paper, is also called the traditional Four Treasures of the Study in China, and it is an essential tool for China's calligraphy. The use of inkstone materials is also very extensive, among which HongLing inkstone in Qingzhou, Shandong Province, Duanyan in Zhaoqing, Guangdong Province, She Yan in Guzhou, Anhui Province, Taohe inkstone in Zhuoni, Gansu Province are the most prominent, and they are called "four famous inkstones".

Liu Xi's Interpretation of Names in the Han Dynasty explained: "Those who write inkstones can study ink, but they can study ink, which makes the messenger flexible.". It evolved from a grinder in primitive society. In the early days, the shape of inkstone was primitive. It is made of a small millstone pressed with ink pills on a smooth stone tool and ground into ink.

By the Han dynasty, there were carvings on the inkstone platform, and there were enough under the stone cover. From the Wei, Jin, Sui and Tang Dynasties, a round porcelain inkstone appeared, which was more than three feet long. The dustpan-shaped inkstone is a common kind of inkstone in Tang Dynasty, similar to dustpan. One end of the inkstone falls to the ground, and the other end is supported by feet. During the Tang and Song Dynasties, the shapes of inkstones became more diversified.

The development of inkstone is introduced as follows:

The inkstone platform, also known as "inkstone tile", is named because it is shaped like a platform and concave like a tile. Shi Ming's definition of inkstone is: "People who study inkstone can study the harmony between ink and ink." Although with the development of culture, inkstone has become a great "elegant object" appreciated by literati, it was only used as a tool at the beginning of its birth, just like a sword and a plate.

Therefore, the early inkstone paid more attention to whether it was strong and wear-resistant. 1980, a set of tools for drawing pottery was unearthed at Jiangzhai site in Lintong, including a stone inkstone platform, which shows that inkstone, as a tool, has a very long history. In the pre-Qin period, splendid culture flourished, and the development of writing and recording technology gave birth to the inkstone specially used for writing.

The development of inkstone in Han Dynasty is introduced as follows:

In the Han dynasty, the shape of inkstone was relatively more exquisite. Most inkstones are round inkstones with three feet, covered, shaped like a small tripod and engraved with simple patterns. In the Han Dynasty, simple inkstones made of local materials were very common, and the slightly modified shapes reflected the Han people's interest in cultural life.
