The "five fingers method" (double bracts) of double hook calligraphy, also called "double bracts", is a writing method. Han, a calligrapher in the Tang Dynasty, said in "Tips for Giving Pens": "The beauty of Fu Shu lies in its principle, that is, it is both a two-finger tube and a five-finger tube. It should be a virtual palm, and it is also called a delivery, preparing for oral delivery. " The method is to press outward with a big point, hook the food with the middle finger inward, expose the ring finger outward, and get the little finger stuck under the ring finger, so that all five fingers will come in handy. Five-finger method is also a kind of "double hook".
In the Southern Song Dynasty, Jiang Kui said in "Continued Book": "The double hook method requires that the pen and ink should not faint out of the word, or the outline should be filled in it, or Zhu Qi's back should be fat and thin." Lu Fangweng, a great poet in Song Dynasty, praised the charm of "double hook" with his quatrains of "Mo Miao's double hook post".
