What font is the calligraphy of the inscription in this lady's painting? Is the author Zhang Pei or Zhang Pei X? I don't know the third word cursive. Do you have a brief introduction to the author?

The calligraphy of the inscription is a running script font, and the author is Zhang Pei. The third word is "book", so it can be seen that the inscription of this painting was written by Zhang Pei, but this painting is not necessarily painted by Zhang Pei. It often happens in some paintings: because the painter's handwriting is not good, he asks others to help him with the inscription, so the person who helps him with the inscription on the painting often writes the words "XX book" behind the inscription. )
