Introduction to the Imperial Huashan Inscription Stele: The Imperial Huashan Inscription Stele is an inscription written by Emperor Xuanzong himself, and is known as "the best stele in the world". Huang Chao's uprising army marched from Tongguan to Chang'an, passed through Huayin and burned the Xiyue Temple, and the monument was destroyed. Today's ruined stele is 3.1 meters wide from east to west, 1.6 meters wide from north to south, and 2.1 meters high. The stele is surrounded by lines carving patterns of mythical beasts. The four characters on the stele's body, "Drive as if Yang is pregnant," are the remnants of the sentence "The immortal drives like hearing, and Yin and Yang are pregnant." . The base of the monument is composed of two huge stones, connected by a line plate made of pig iron in the middle. Surrounding the base of the monument are reliefs of a 1.6-meter-tall warrior in golden armor.
