"Cai Gen Tan" was written during the Wanli period of the Ming Dynasty, which has a history of nearly 400 years. The author Hong Yingming, whose courtesy name is Zicheng, is also known as the First Taoist. He was keen on career success in his early years. In his later years, he retired to the mountains and forests to devote himself to reading and writing. Finally, he put his life experience, reading experience and life insights into the tip of his pen and poured ink into this eloquent collection of more than 300 well-proportioned quotations.
