How to evaluate Mr. Qi Gong?

Mr. Qi Gong's calligraphy is good at regular script, but neglected cursive script. Regular script turned into a master, and finally became the closest master calligrapher in China who could contribute to fonts. His calligraphy style seems ordinary, but in fact it is calm and sophisticated, with little change, but there is no disadvantage at the turning point; Although his paintings are conservative and old-fashioned, his attitude is serious, his techniques are complete and his effect is simple and fresh. On the whole, Qi Lao's artistic creation is in an extremely conservative quadrant, but the old man has made his own unique achievements step by step in this quadrant. This is enough to be an example.
