How to objectively evaluate Fan Zeng?

From Fan Zeng’s calligraphy and paintings, we can see his outstanding art skills. Although Fan Zeng's calligraphy and painting are considered by many to be too dogmatic and the same. But from the perspective of art techniques, Fan Zeng's calligraphy and painting standards are still good. As an artist, Fan has a legendary past. This also shows Fan Zeng’s integrity as an artist and his rare independence and pride. But over the years, Fan Zeng, who returned to China, seemed to have embarked on a different path, which was very different from before. In the author’s hometown of Tianjin, Fan Zeng’s inscriptions can be seen everywhere. Mr. Fan's calligraphy can be seen in everything from real estate, enterprises, private hospitals, high-end restaurants to halal hotpot mutton. Fan Zeng, who spent his evening life peacefully, also drove a top-notch luxury car and lived in a mansion. He also accepted many celebrities and wealthy people as his disciples. The art master who was once admired by others, while continuing to get rich, seems to have become a cultural craftsman who "mingles in high-end circles". Fan Zeng's development turn like this can't help but feel regretful.
