Appreciation of calligraphy is a little higher than that of painting. Everyone knows a regular script, but most people don't know cursive script and seal script. Some things are not difficult to identify, and ordinary people without professional knowledge may not know. Calligraphy is an abstract beauty, which requires the appreciator to have an overall knowledge and understanding of the art of calligraphy. This standard is relatively high. For example, we read a word, and professionals read a work, saying this word is really good. Perhaps most non-professionals think this word is so ugly, why do you still say it is good? This appreciation may be relatively difficult. Painting is relatively more intuitive and concrete, painting mountains and water, painting people. For example, Zhang Daqian painted meticulous figures, which are fine and beautiful, and everyone feels fine. This is easy for everyone to agree with, and calligraphy may be relatively difficult. In this regard, calligraphy still has a relatively large market space for cultivation. In recent years, the study area has attracted more attention or the price increase is relatively high. One of the main reasons is that many buyers with certain cultural tastes have participated in this market.
