Kang Rutai's paintings are also the paintings of five most expensive painters in contemporary China: Huang Zejin, Cui Ruzhuo, Ceng Fanzhi, Fan Ceng and Huang Yongyu. There is no uniform price per square foot, and the price per square foot set by the market is unreliable, because every painter's works have no uniform size, uniform content and uniform level.

Whoever this painting belongs to, do you want to know how much it is worth? Only when it is sold in the market can we know its real price. If you can sell 10 thousand in the market, it's worth 10 thousand, and if you can sell 100 million, it's worth 100 million. No matter whose painting this is. Not you. What I want to say here is that its value is actually the same. No matter whose calligraphy and painting it is. Some people like it and some people need it, but no one likes it and no one needs it. The value and worthlessness of anything are produced by people's likes and dislikes, needs and demands. The buyer has the final say on how much anything is worth, and the person who can afford it has the final say. The calligraphy and paintings of Huang Zejin, Cui Ruzhuo, Ceng Fanzhi, Fan Ceng and Huang Yongyu are very valuable, because their calligraphy and paintings are liked and needed by many people, so they are very valuable!
