Isn't it rich for calligraphers to write and sell every day

Calligraphers write and sell every day, but they often say that they have worked hard for more than ten or even decades to practice Chinese calligraphy (or calligraphy), but they are still poor. I have personally contacted many calligraphers, some of whom can't even afford rice paper. Undoubtedly, the calligraphy and painting market in China has been extremely hot in recent years. Under this excellent situation, our calligraphers still do not rely on calligraphy as a craft to live a luxurious life.
