This work is the work of Mr. Jing Shijiang, a famous hard pen calligrapher. Due to the popularity of computer software, Mr. Jing's fonts are widely known because they are included in the "ancient and modern calligraphy master font library". The word "Zi" expresses a free and easy feeling, which is a work style that I personally appreciate.
Because the overall structure of the word "Zi" is relatively square, it is very suitable for running script. As long as the practice is in place, how to write is beautiful.
