Ask the calligraphy teacher why there are faint traces after writing brush strokes. Does it affect calligraphy? Can you remove this mark?

The handwriting is very good. In places where the pen is carried slowly and the residence time is long, the ink is wet outward. This is not allowed in calligraphy works. As a calligraphy work, it has been invalidated. It can't be repaired. The ink was taken away when it was poured out. 1, the pen speed should be accelerated and the ink should not be too full. The ink concentration is not enough, so you can use the ink you bought. 3. When writing calligraphy works, you should grind the ink yourself until the ink is pushed forward quickly and a small alley appears in the ink (wait a little while, the ink will flow back) before you can use it to write calligraphy works. We all use ready-made ink now, and we can't sayno. Generally, we solve it through some technical means, such as using pen speed, so that our works can't be printed. For reference only.
