How much is the dragon in the desert worth now?

The four-foot painting of the desert dragon is 20,000 yuan, the six-foot painting is 50,000 yuan, and the four-foot painting 10000 yuan. But recently, I announced that I would no longer write a "dragon" pen. In addition to the day when the dragon looked up on February 2, there was also the first day of June. I wrote a picture for myself and stopped writing it outside.
