How long did Wang Xizhi practice calligraphy, and then he used a forceful pen, which failed him?

Wang Xizhi is very energetic in practicing calligraphy. No matter what season, what weather and what happens, he doesn't care. In less than three years, his words were forceful and depressing. Wei Shuo was very happy to see him and praised him: "This child's calligraphy grows really fast, and he will be more famous than me in the future."
