From the Han Dynasty, the "monument" and "monument" were also called "tombstones", which were made by punching holes above the monument and guiding the coffin into the cave with ropes, and erected at the tomb door at the end of the Western Han Dynasty. At that time, square ones were called monuments, and round ones were called monuments. After the Tang Dynasty, the stele used more than five products, and the stele used the following. To later generations, steles are often universal.
There are two interesting jokes about tablets. Record:
In Xi 'an's forest of steles, there is a preface to Tang Sanzang. Every word was indeed written by Wang Xizhi, a great calligrapher in Jin Dynasty, but the content of the inscription was written by Emperor Taizong Li Shimin for Xuanzang, a monk. What's going on here? It turns out that Li Shimin of Emperor Taizong and Li Zhi of Tang Gaozong loved Wang Xizhi's ci very much. They wrote to the whole country, collected the king's works from many sources and treasured them in the palace. There was a monk named Huairen, who was proud that the emperor could write articles for monks and admired the calligraphy art of previous calligraphers. He is determined to combine the calligrapher's calligraphy art with the emperor's articles. So, he led his disciples to spend 20 years searching hard, and finally collected Wang Xizhi's words one by one according to the preface of the "Preface to the Holy Teaching" and engraved them on this ancient monument.
In the Tang and Song cultural sites in Renshou County, Sichuan Province, two rare invisible monuments in China were newly discovered. At the bottom of the rock wall surrounded by water, there is a headless stone dragon more than ten meters long. There are statues of the Dragon Throne carved in the Tang Dynasty and inscriptions carved since the Tang, Song and Ming Dynasties. Only the dragon throne is like a stone niche, with wall tablets embedded on the left and right sides. The surface of the stone is smooth, spotless and gray, with no carving marks or ink marks. However, after splashing water, the big characters of black ink appeared on the right panel, which was clearly identifiable; On the left side of the monument, there is a thick and thin leaf ink bamboo picture, which disappears with the air drying of water. According to the Records of Renshou County, the calligraphy and painting of the intangible tablet were written by the cousin of Su Dongpo, a famous calligrapher, painter and essayist in the Song Dynasty. This steganography is still a mystery.
