What is the secret of Wang Xi's writing?

Wang Xizhi's intelligence was not outstanding when he was a teenager. But since I studied calligraphy with Mrs. Wei at the age of seven, I have been able to persist in studying hard and practicing hard. According to legend, he practices calligraphy every day, even when he is resting, he is trying to figure out the structure, shelf and momentum of the font, while scratching his skirt with his hand. Wang Xizhi often practices calligraphy by a pool at home, taking water from the pool to grind ink, wash pens and brush inkstones. Over the years, it turned a pool of clear water into black. There are still "Mo Chi" relics in Wang Xizhi's former residence, and "Linchi" has become synonymous with Xi Zi.

With the growth of age and broadening of horizons, Wang Xizhi is not satisfied with the reference of a monument and a post, and the guidance of one or two teachers. He wants to learn from others and form his own style. On the basis of learning from the past and the present, Wang Xizhi changed the methods of flat seal and official script before the Jin Dynasty and created three kinds of fonts with personal style: elegant and chic running script, vigorous regular script and flying cursive script. Wang Xizhi also taught his son Wang Xianzhi, who also loves calligraphy, his personal experience of studying hard and practicing hard. According to legend, when Wang Xianzhi began to copy his father's calligraphy, he asked his father what the secret was. However, Wang Xizhi pointed to eighteen water tanks in the yard and told him that the secret was in these tanks. When you finish writing these eighteen jars of water, you will naturally know where the secret is. Wang Xianzhi follows his father's instructions and takes water from the jar every day to grind ink and practice calligraphy. A few years later, he really used up eighteen cans of fruit. Wang Xianzhi's calligraphy has been greatly improved. Finally, he created Modern Grass with exquisite structure and beautiful font, and became a great master. Like his father, he was called "Two Kings" and "Little Sage".
