1. Writing posture: the writing brush is "five-finger writing", that is, the thumb, index finger and middle finger hold the pen, the ring finger and little finger press against the back of the pen, and the pen is perpendicular to the paper.
2. Post selection: To copy Cao Quanbei, you can choose the original rubbings such as Xi 'an Beilin Museum or Duoyunxuan Collection.
3. Copy: first read the post, observe the strokes and structural characteristics of the words, and then start writing, thinking while writing, and practicing repeatedly.
4. Structural features: mainly flat potential, horizontal potential and zigzag stretching.
5. Stroke characteristics: the horizontal strokes are parallel, the spacing is even, and the pen is vertically downward.
6. Radicals: The upper and lower proportions and sizes of the left and right radicals are basically the same, and the characters with upper and lower structures should pay attention to the characteristics of tightening up and loosening down.
7. Word collection practice: combine the learned words into a paragraph for writing practice.
In a word, the writing of Cao Quanbei official script needs to pay attention to the characteristics of structure, strokes and radicals. Only by copying and practicing can we master its essentials.
