Song Lu You's poem "Living in seclusion without guests, the day is just a long sentence with pen and ink": "The water is heavy and the guests are scarce, and the four gentlemen in the study depend on each other."
Pen, ink, paper and inkstone are collectively called "Four Treasures of the Study". The ancients believed that everything was spiritual, so was pen, ink, paper and inkstone. In addition to use, the literati also gave them humanized names (see Han Yu's Biography of Mao Ying):
Pen: Zhongshan, Mao Ying. Zhongshan, the name of an ancient vassal, was destroyed by Zhao during the Warring States Period and is now Dingzhou, Hebei Province. According to Wang Xizhi's Bi Jing, in the Han Dynasty, governors, counties and countries all over the world competed to write the plaque on the Hongdu Gate in Luoyang with rabbit brush. As a result, only Zhao Rabbit's brush was selected. Zhongshan belongs to Zhao, so it is called Zhongshan people, and "Ying" refers to the conical brush. Some people are also prolific because of Xuancheng, also known as Xuancheng Mao, the word Wenfeng.
Ink: Crimson Hsuanchan. In ancient times, Jiangzhou was in Xinjiang County, Shanxi Province today. The ink produced is famous as a tribute to the court, and the ink is above the old and thick black, so it is called craftsman Chen Xuan. Also: Li Tinggui, a Yan man in the Southern Tang Dynasty, used pine smoke as ink, which is most famous for its luster. After crossing Yishui, he lived in the south of the Yangtze River, so some people called Mo Yi Xuanguang, Yan Ren, and the word was dark.
Paper: I want to learn from Chu. In ancient times, it was recorded in Shaoxing, Zhejiang Province that tribute paper was produced there. The bark of Broussonetia papyrifera is the first-class raw material for papermaking, and Chu and Broussonetia papyrifera are isomorphic, so some people take "Chu" as the surname of paper from people's surnames, which is called the white of Chu in Huiji. In addition, some people call Chu Huayin because he produces more paper in Huayin, Henan, and his words are mysterious.
Inkstone: Hongjia Taohong. During the Sui and Tang Dynasties, pottery inkstones prevailed in the world, among which Zhou State, namely Hongjia County (now Lingbao, Henan Province) in the Han Dynasty, was the most famous, and the middle depression of inkstone was used to store ink, so it was called Hongjia Tao Hong actress, born 1969. Some people also say that stone makes inkstone, and there is emptiness in the stone, and the words are silent (ink).
The ancients not only gave names to pens, ink, paper and inkstones, but also sealed official positions. Pen: writing supplies, because the pen holder is a bamboo tube, it should be dipped in ink when used, so it is named Zhongshujun, Guanchenghou, Cao Mo Dutong, Mojunwang and Maozhu Temple; Ink: pine smoke is mostly used as raw material, and high-quality spices are added, so it is named Songzihou, Black Pine Messenger, Xuanxiang Taishou and Bozhou Junpingzhang. Paper: elastic, can be cut at will, white is better. Therefore, sealing paper is a good way to serve (serve) Hou, museum history, Baizhou history and military strategists. Ink stone: a container for storing ink, which is hard in texture. He was named Jimo Hou, Lishi Hou, Iron Face Shangshu and Jimo Military Commander.
