Who did Jiang Wen learn calligraphy from?

Jiang Wen is good at calligraphy. The biggest highlight is that he is also good at "hairstyle", which is not a font that ordinary people can control. Even calligraphers should stay away from it and dare not touch it easily. However, under the pen of director Jiang Wen, he wrote a fresh image, which not only wrote a dignified "hairstyle", but also wrote the spirit of "pointing the country", as did Jiang Wen's cursive script. Zhao Ti's words are free and easy, and at the same time, he is slightly determined by Fang Bi. This Fang Bi phenomenon is also very obvious. I think I borrowed Weibei. From this perspective, he is also a director who is good at reading posts. For such a director, it is also a very rare thing to be able to calm down and study calligraphy.
