How much is the work of Bird Siguang, a member of Xi Calligraphers Association?

As long as it is a good work, it costs at least several thousand yuan. At the same time, the hero doesn't ask the source. Moreover, everyone's calligraphy is good and bad, valuable and worthless, expensive and relatively cheap, and Runge has no definite goal, just a reference, mainly depending on his own judgment and understanding of his calligraphy and painting, as well as the hype in the market at that time. Also, as long as the words are good and you like them, they are valuable for collection. They don't have to be famous now, but they must have their own characteristics. The calligraphy and painting of Zhu Da, a native of Badashan Mountain, lived only for food and became famous after his death. Up to now, his calligraphy and painting are all national treasures. There are too many such examples. My own opinion, please forgive my mistake!
