1. The term "red earth" refers to the secular world. In ancient times, the word "Red Dust" originally meant a prosperous city. From the poem "Ode to the Western Capital" by Ban Gu, a writer and historian of the Eastern Han Dynasty: "The city of Khotan overflows the country, and hundreds of dust flows beside it. The red dust is everywhere, and the smoke and clouds are connected." The general idea is that "the dust (red dust) raised by the lively and noisy flow of people" ), gathered from all directions and filled the whole city, and the dust and smoke were all connected together." Later, "red dust" evolved into "the bustling dust market", which was used to explain the "human world" and was first used by Buddhists in Buddhist scriptures. The word "red earth" referring to the mortal world appears in many places. The opening chapter of "Dream of Red Mansions" explains the origin of the stone: "It turned out to be a stubborn stone that was brought into the world of mortals by the vast master Miaomiao Zhenren who had no talent to patch the sky, and was led to the other side." This mysterious description, It is a mythical story from Buddhism.
