Extended information:

Tang Bohu, later changed to Ziwei, also known as Liuru Jushi, Taohua Temple Master, Tang Sheng of Lu State, Fleeing Zen Immortal Official, etc., was under the jurisdiction of Wuxian County, Suzhou Prefecture in the south people. Famous painter, calligrapher and poet in Ming Dynasty.

Tang Yin’s ancestor was Tang Hui, the former general of Lingjiang in Jinchang County, Liangzhou. This also directly affected Tang Yin. He also often used the inscription "Jinchang Tang Yin" in his calligraphy and painting titles. In the early Tang Dynasty, his ancestor Tang Jian followed Li Yuan in raising an army and was named "Gong of the State of Ju", so Tang Yin also called himself "Tang Sheng of the State of Lu". In the Ming Dynasty, his ancestor Tang Tai served as the chief chariot driver of the Ministry of War and died in the battle of Tumubao.

Most of the descendants of Tang Tai lived in Baixia and Qiaoli, Wuxian County, Suzhou. Tang Yin was also born in this area, and his father Tang Guangde ran a tavern. His father asked him to study in order to gain fame. Tang Yin lived up to his father's expectations. At the age of sixteen, he was the first in the Suzhou Prefectural Examination to study in Xiang. At the age of 28, he ranked first in the Zhongnan Zhili Township Examination, and the following year he entered Beijing to take part in the joint examination. In the twelfth year of Hongzhi's reign, he was implicated in the imperial examination and was demoted to an official. Unexpected changes caused Tang Yin to lose his ambition. From then on, he wandered around the world, buried in poetry and painting, and eventually became a famous painter.
