First of all, we can be sure that this is a commercial activity, conceived by smart people and people with economic minds. Their propaganda wrote this mat on the surface, which has a certain auxiliary effect on the creation of hard-pen calligraphy, and is of great help to improve the level of water calligraphy, and even has obvious effects. In fact, as a result, all these people made money and won. Then let's analyze the application of this kind of summer sleeping mat in actual writing. We know that simply taking out a piece of paper and spreading it directly on the table feels hard and uncomfortable, which is tolerable for ordinary writers.
But for those who practice hard-pen calligraphy or even hard-pen calligraphy, it is simply a torment, which will be very uncomfortable, so most people will take out more than a dozen pieces of paper when writing, write a piece of paper on it, and the paper below can be used as a cushion. So I can write easily. This is because the tip of a hard pen is hard, and writing on thick pad paper has a little flexibility, which can not only have different strokes, but also bring a pleasant feeling to the writer.
When writing, you should prepare newspapers and books of appropriate size under both writing paper and writing paper. As for the function of special hard pen calligraphy pad in practicing calligraphy, I can definitely answer that it is useful. We can imagine that it is much better to put this mat under a piece of paper than nothing, but the material of this mat is too soft, and if you write on it, it will puncture the paper. I think it would be better to put some magazines on it.
