Mr. Yang Gen's "On the Eight Kilns System in Song Dynasty" should be the same as your paper, which should be regarded as a simple summary of ceramic archaeology in Song Dynasty. Besides, there are some mistakes in it. For example, he thinks that the glaze of Dingyao white porcelain can hide the soil, but in fact, it is found through experiments that it is a mullite crystallization phenomenon under special firing conditions. Therefore, I hope that the landlord will not be too nervous when doing this paper. Since I am writing a paper and an archaeological paper, I want to add something to facilitate the landlord to write a paper. Since the landlord is studying archaeology, he should know that when discussing some artifacts in the archaeological sense, he should explain the origin and destination of these artifacts clearly, so I want to add: What did the jade articles in the Tang Dynasty embody before and what did they affect later? From the shape point of view, jade handed down before the Tang Dynasty, in addition to common ritual vessels, ornaments, containers, there are new vessels such as jade books. Some traditional types of utensils, such as archery (not this word or that word in my dictionary, which means pulling fingers), have been popular since the Warring States period, flourished in the Han Dynasty, and continued to be used in the Northern and Southern Dynasties. But in the Tang Dynasty, there was no such thing in Guanzhong area at present, so it can be seen that such a thing should be in the Northern Zhou Dynasty. It influenced the emergence of new jade varieties in the Tang Dynasty, such as Tian Fei and other Buddhist jade articles, which are representative works of carving jade articles by round figures in the Tang Dynasty. We can notice that there were few jade carvings before the Tang Dynasty, but these things suddenly increased after the Tang Dynasty, and the styles of jade carvings in the Song and Ming Dynasties were basically not much different from those in the Tang Dynasty, which is very noteworthy. On the processing technology, on the one hand, it continues the traditional grinding and cutting technology of jade articles in the Tang Dynasty, on the other hand, the point, line and surface continuous carving technology that once appeared on jade articles in Qin State has been innovated, which should be related to the popular carving technology of gold and silver vessels at the same time. If we analyze the help of short and thick lines in the Tang Dynasty to artistic expression, we can easily find that this kind of negative line well shows the vigorous muscles of relief figures or animals on the jade belt ornaments unearthed from hejia village and Chang 'an Xue tombs, which is consistent with the aesthetic view of taking fat as beauty in the Tang Dynasty. The exquisite combination of gold and silver vessels and jade articles reached a peak in the Tang Dynasty, and this decorative technique appeared in the pre-Qin period. However, in the Tang Dynasty, gold and silver were most commonly used for jade decoration. It should be noted that in the pre-Qin and Han dynasties, jade had a strong ideological symbolic significance, but gold and silver were rare, so jade was very common in the cultural circle of the Central Plains. There were so many gold and silver in the Tang Dynasty that the combination of gold and silver should be a manifestation of the opening up and national integration in the Tang Dynasty. In addition, the types of jade materials in the Tang Dynasty are also extremely rich than before. During the pre-Qin, Qin and Han dynasties, the traditional jade and stone materials in China were mainly nephrite, agate, crystal, car paint, turquoise and jade, but precious stones began to appear in the Tang Dynasty. That's what I want to add. Besides, I'll give you some advice. Unearthed jade articles in the Tang Dynasty show that, except for displaying jade articles, the types of jade articles worn with you are very single, and the craftsmanship is even inferior to some fine articles in the pre-Qin period. Although this is related to the change of Chinese jade concept since the Six Dynasties, there should be other reasons. I think your paper should be very profound if you can see through some ideological aspects of jade in Tang Dynasty from its morphological description. If we can study the jade unearthed in the Tang Dynasty by stages and regions, the explanation of the cultural mentality change from opening to closing in the Tang Dynasty before and after the Anshi Rebellion will be more perfect.
