What does Shan Tianfang mean when he says that the immortals are hard to come by in a flash?

Lu Zhishen, Hua Monk, used to be called Lu Tiha by his neighbors. He took off his upper body and could see patterns and embroidery all over his body. He was beaten to death by Zhen Guanxi with three punches and ran away to avoid trouble. , and later became a monk at Wenshu Monastery in Wutai Mountain, so he was nicknamed "Flower Monk" in the world.
Some people say: "It's mainly because he eats meat and kills people. It's like a monk's commandments. If he doesn't abide by any of them, such a monk is called a flower monk." This is wrong. There are many precepts for monks, but not all of them were violated by Lu Zhishen. Taking the most basic five precepts as an example: "Do not kill, do not steal, do not commit sexual misconduct, do not lie, and do not drink alcohol." Lu Zhishen only violated two precepts: killing (eating meat can be classified as killing) and drinking alcohol. He did not violate the other three precepts. At least theft and sexual immorality were what Lu Zhishen hated deeply.
The reason why Lu Zhishen is called the Flower Monk is mainly because of the flower embroidery on his back.

When Naian first conceived Water Margin, he tried to portray Song Jiang as a Liu Bei-like character, and at the same time, he also brought in a whole team of people around Liu Bei. Wu Yong and Guan Sheng assumed the roles of Zhuge Liang and Guan Yu respectively, and Lin Chong was naturally the incarnation of Zhang Fei.
Lin Chong's nickname "Leopard Head" comes from Zhang Fei's appearance: "eight feet in length, a leopard's head with eyes, a swallow's chin and a tiger's beard". Lin Chong's weapon also has eight snake spears. During the second attack on Zhujiazhuang, Mr. Shi Naian gave a more thorough explanation: "Everyone in the mountain calls me Xiao Zhang Fei, and that's Lin Chong, the leopard head."
