The town of Suzhou, famous for its gardens and canals, was also one of the main cultural centers in China, attracting many painters, calligraphers, poets, musicians and other talented individuals. Their pursuits and interests form the main subject matter of the group of acclaimed jade and agate carvings executed in a style unique to the area. It was in Suzhou, during the late Ming dynasty, that the workshop associated with Lu Zigang was established. The carvings produced by Zigang during this period were regarded as being of the highest quality throughout the Qing dynasty, and many later carvings bear his name.
