What was unearthed from Mawangdui Han Tomb No. 3?

According to current data, the large number of silk scripts and bamboo slips unearthed from the Mawangdui Han Tomb are the most representative in reflecting the official changes in writing in the early Han Dynasty. "Combining Yin and Yang" is a bamboo slip unearthed from Tomb No. 3 in Mawangdui. The owner of Tomb No. 3 in Mawangdui died in the 21st year of Emperor Wen of the Han Dynasty, that is, 288 BC, only 38 years after the founding of the Han Dynasty. Also unearthed from the same tomb as "He Yin and Yang" are four kinds of bamboo slips with different contents such as "Ten Questions", "Tianxia Zhidao Tan", "Miscellaneous Forbidden Prescriptions", and "Qian Ce", as well as silk books with other contents. "Integrating Yin and Yang" has three or two bamboo slips. The length of the bamboo slip is about 2 to 3 centimeters, and the width of the bamboo slip is more than one centimeter. The text on each bamboo slip ranges from more than 20 words, and its content is about maintaining health in the house. The description of the specific techniques of the surgery belongs to the medical slips. This batch of slips is wider, which facilitates the use of calligraphy skills when writing. The copyists of this batch of bamboo slips also had high attainments in calligraphy. Judging from the strokes of this set of slips, the writer can combine different hard and soft strokes at will. For example, although his horizontal paintings, like the text on the "Qian Ce" in Tomb No. 1 of Mawangdui, pay attention to the square starting point and the sharp end, the square starting point often has a round pen or dotted ink. I don't care too much about whether the edges and corners are clear or not. As for the folded pen, the square and the circle are equally emphasized, or one stroke is bent down to show its roundness and smoothness, or the divided strokes are connected to show its strength and strength. Judging from the structure of the text, the palace is compact in the middle, stretched around, avoiding the left and right, echoing up and down, and looking forward to the sentimental. Especially where the waves are draped, they are full of energy and can do their best to bend and pitch the waves, which has a special connotation of wonderful changes. Looking at the overall layout, the black-and-white layout within the simple text is natural, sparse and smooth, without any craftsmanship, but appears to be brilliant and pleasing to the eye. Therefore, no matter how you evaluate it, the calligraphy art of this batch of bamboo slips is the best among the calligraphy arts of Han bamboo slips.
