Is the calligraphy of Su Shi's "Queen Qi Jufu" authentic?

It's true. After Lu Guimeng, Su Shi, a poet in the Northern Song Dynasty, wrote a post-Qi Ju Fu, mocking himself and rewarding himself: "I regard Qi as food and living in embarrassment. Eating seedlings in spring, leaves in summer, flowers in autumn and roots in winter is almost the life of Xihe Nanyang. " The Post-Life Fu is a "self-deprecating" essay by Su Shi in the Northern Song Dynasty, which was written during the period when the poet was the magistrate of Mizhou.
