Lu Jianzhi majored in Yu Shu. Although later theorists thought that he was not as good as his uncle, he asked Wang Xizhi for help, which was different from Shinan. From Lu Ji's book "Wen Fu", we can see that Lanting still has the charm of Jing Ya, but it only adds moist beauty. Look at his pen. When he started writing, he still had the dignity of regular script. No matter how he stippled, he entered the pen. It is neither too late nor too sick to write, which can not only polish up, but also be beautiful and not sluggish. Moreover, the pen is alternately clear, the front is properly closed, and occasionally it is returned. But it does not hinder the perception and echo between words. It is particularly noteworthy that the structure is different and extremely coordinated. Sometimes there is regular script, sometimes there is running script, and the steps are relaxed, graceful and mature, and sometimes there is cursive script, which is convenient and simple, and even Cao Zhang's brushwork can be seen occasionally. There are large and small glyphs, which are horizontal and vertical, patchwork and interesting, making people feel relaxed and sloppy, but they feel that Watson is between the lines. Beginners who are learning to run calligraphy have a lot of convenience from now on, which can be a transition from writing to writing. If you can study hard, its beautiful and moving book style and steady and smooth charm will give people many new territories.
