No, it was Monk Huaisu, a great calligrapher of the Tang Dynasty.
Huaisu cultivates bananas and learns calligraphy
Monk Huaisu, a great calligrapher of the Tang Dynasty, wrote very well in cursive writing. He has been practicing calligraphy under extremely difficult conditions since he was a child, and he has never been discouraged (něi). When Huaisu was a boy, his family was poor and he was sent to a temple to work as a monk to earn a living. However, Huaisu, who was naturally studious, loved calligraphy in addition to chanting sutras. The senior brother saw that Huaisu loved calligraphy so much, so he gave him a writing brush. Huaisu picked banana leaves as paper, and used the soot and water under the iron pot as ink to study calligraphy. Later, in order to practice calligraphy with banana leaves, Huaisu planted a large number of bananas outside the garden. In winter, Huaisu also found a thick wooden board to make a lacquer plate, and wrote and erased on it. Over time, the lacquer plate was wiped clean.
