Is Yin's calligraphy and painting valuable? About more money per square foot.

I collected it. I'm a fan of her. As far as I know, Yin is the third generation painter of Qi School. Her two-handed painting is a must, with high artistic value. At the same time, she is also an actress and singer, making movies and TV series and releasing songs. Her calligraphy and painting rarely appear in the auction market. I once learned that her 4 square feet of shrimp have been sold to 1.2 million yuan, and the market price is more than 300,000 yuan per square foot. Her calligraphy is unique, and the unit price per square foot exceeds that of Fan Ceng's works on the market. If you don't believe me, you can find an appraiser of an auction company or an appraiser of a TV program. Ordinary antique shops and auction companies that only accept the membership of famous artists may not know the market. She is a super potential stock in calligraphy and painting.
