Dai calligraphy

It is suggested to watch Li Tiansheng's calligraphy video, and it is also important to choose a pen suitable for writing Chinese characters, otherwise it will be difficult to write the characteristics of Chinese characters. It is suggested to search for "hand-polished nib" in Taobao. The pen inside is specially polished for writing Chinese characters. It can be written for seven days when bought, but I don't like the boss to return it. The price is not expensive either. The cheapest one is only 15 yuan.
