This shows that it is not only a tribute to North Korea, but also meets the needs of the general public. In the 9th century A.D., it was recorded in Yuefu Miscellaneous Notes of Duan 'an Festival that Guo Daoyuan, a musician in the early Tang Dynasty, "added and subtracted water with the twelve names of Yueou and Xingou, and struck it with a plate, and its sound was better than the square sound." Tendons are chopsticks. This passage shows that Xing kiln white porcelain is of good quality, its fetal bones are solid and dense, and there is a stone sound when it is struck, so it can always be used as a musical instrument together with Yue kiln porcelain (Xing porcelain is probably used as a high-pitched part), and pottery is absolutely inferior. As we all know, during the Warring States Period, there was a story about Lin Xiangru's return to Zhao intact. Lin Xiangru, the doctor of Zhao, forced the king of Qin to strike. This blow was a clay pot, which embarrassed the king of Qin and safeguarded Zhao's dignity.

In order to illustrate the position of Xing Kiln, I quoted the viewpoint in Tea Classic by Lu Yu, a monk in the Tang Dynasty.

Lu Yu said, "Or if Xingzhou is located in Yuezhou, it will be different." It is not difficult to see that there was indeed a view that "the stars were born on the moon" in the society at that time. Lu Yu is a southerner and likes to drink green tea. Praise is his personal preference, so this statement only represents his own point of view. Look at Lu Yu's ranking of kilns. Xing kiln is also in a parallel position with Yue kiln. Look at the three things that Lu Yu said: "First, Xing's silver is not as good as Yue's jade; Second, Xing's snow is not as good as ice; Third, it is not as good as Tan Qingyi. " This can be said to be his personal likes and dislikes. Objectively speaking, it is hard to say that "jade wins silver, ice wins snow, and green wins Dan" is the only standard. Many people think that everyone has his own strengths and everyone can have his own strengths. Lu Yu simply compared Xing Kiln to Yue Kiln, indicating that Xing Kiln really shook the unified position of Yue Kiln.
