Excuse me, there are watercolors, oil paintings, Chinese paintings and meticulous paintings on the market now. Which of these paintings sells best? The most profitable? thank you

Oil painting is the best seller, but Chinese painting is the most profitable. Compared with the two, the theme of oil painting is richer, and the scale can be changed as needed, so the scope of decoration is wider. For example, any small fast food restaurant can get an oil painting to adjust the color, but you don't often use Chinese painting because Chinese painting pursues artistic conception and the color is more elegant. Why is Chinese painting more profitable? Because there are too few high-quality products ... if you really create first-class Chinese painting and do it right, you can be very leisurely in a few years. Hehe, just take time to play oil painting.
