How is Ren's calligraphy? Is it worth collecting?

The landlord wants to start? Or do you already have his calligraphy works? If you have it, collect it well, don't wait for the money to be used. The same calligraphy works are not equally valuable, and Zhang Daqian's paintings are not very valuable. The key is to look at the artistic achievements represented by the works. The landlord should have noticed before: a calligrapher's later works can represent the calligrapher's later changes and the highest artistic achievements, and the collection space is very large.
