What did the ancients say about five trillion yuan?

An ancient method of divination. Records of Emperor Taizong in Old Tang Dynasty: "All kinds of divination have stopped except tortoise, Yi and Wu Zhao." Song Mei Yao Chen's poem "Mixed Feelings in the South of the Yangtze River": "Worry comes to five trillion, worship trees and compete with yellow dolphins." Song Zhao Wei Yan's "Money at the Foothills of Clouds" Volume 1: "Fold a bamboo, it is three inches long, play with your hands for good or ill luck, and live five trillion years, which means burning a turtle."

In addition, there are five trillion decline of heaven and man. One is the dirt on clothes. Second, China has withered. The third is sweating under the armpit. Fourth, you stink. Five unhappy.
