Taobao opened a calligraphy shop. How can the pricing be appropriate?

Calligraphy works are mainly priced according to the popularity of calligraphers. If you have ever worshipped some famous calligraphers or won prizes in calligraphy competitions, please indicate in your works that the pricing can be more expensive. Without the above capital, you wouldn't have a six-year calligraphy career. At first, we can only try to price according to the cost of paper and ink plus a little manual fee. When there is a certain market, the price can be raised. Regarding the problem that low pricing will lead to complaints, your own works are legal regardless of the price.
