What kind of tea set is "Chang Shao Shao", which even tea ceremony masters have a special liking for?

"Changbanshao" is one of the six ancient kilns in Japan. It is located in Changhua City, Aichi Prefecture, Japan. It has a history of thousands of years and has been designated as a national traditional handicraft in Japan. Tea sets that are often burned by sliding are like Yixing purple sand in China in Japan, so they are also called "Japanese purple sand". Changshicheng has gathered a group of pot-making masters known as "national treasures of the world", and their tea sets are either gorgeous, exquisite or quaint Gu Zhuo, with ingenious shapes and great practical, ornamental and collectible values. They are one of the popular tea-making tools in Japan and China. (visiting at home)

Japan imported a famous hand-made teapot with a horizontal hand and a side handle for Japanese tea sets.
