Hu Tang (1759-1838) was from She County, Anhui. Hu Tang has a calm personality, does not admire merits and honours, likes to chant, and is particularly fond of seal cutting. In the fifty-eight years of Qianlong (1793), Hu Tang went to Beijing to intersect with the great poet Zhang Wentao. He carefully engraved a "ship mountain" lion button jade seal. Zhang was very happy and gave a long sentence in return.high 7.5cm ,wide 4cm
