This small line of regular script, vertical 3 1, horizontal 37 cm, has hidden spaces, and the book has three lyrics. Now it's in Shanghai Tong's office. The fine print is very precise, and the spirit can be seen in every stroke. The pen is tight, the strokes are heavy and light, the strokes are clean and tidy, and the structure is mostly sideways, so it fluctuates. Although it is a small work, it is a masterpiece that is very eye-catching and worth tasting.
