There is a famous saying in the preface of Li Shimin's holy teachings.
Non-lotus nature is self-cleaning, while cassia seed is true and good, and small things can't be tired; It depends on purity, so turbidity can't be touched.
This is not to say that lotus is clean, and osmanthus is chaste. It is indeed because the attached conditions of osmanthus are already high, and those humble things can't hurt it; Lotus used to be very clean, so those dirty things can't defile it.
It is not difficult to introduce the running script with the preface to the holy teachings. Preface to the Holy Teaching was collected by Huai Su, a descendant of Wang Xizhi, for decades. The hardships can be imagined. Among them, there are both Wang's running script and a small amount of cursive script, which have been passed down to this day and can be said to be the basic introduction of a running script.
Of course, because it is a flat plate, after so many years of wind and rain, many places will be deformed, and it will definitely be a bit difficult to copy for the first time. Many people on the internet have written videos of the holy religion, which can be used for reference. Teacher Chen Zhongjian's special calligraphy video is 500-600 minutes long, and it is full of words. I can understand a lot after reading it, and it's free.
Preface to the Holy Religion is the full name of Preface to the Holy Religion in Tang Sanzang, written by Emperor Taizong. Many people have written the article "Preface to the Holy Teaching". It was first written by Chu Suiliang, one of the four great calligraphers in the early Tang Dynasty, and it was called Preface to Wild Goose Pagoda. Later, Shaman Huairen collected words from Wang Xizhi's calligraphy and carved them into inscriptions, which were called Preface to the Right Army of Tang Dynasty or Preface to Wang Xizhi's Huairen.
