Chinese Zisha teapot, Yixing clay pot, Classical Xishi teapot, this is a very good Chinese Yixing teapot. It was shown that it was wet and its moisture was sucked away, indicating that it was genuine Yixing clay.
Tight seal: When pouring water out of the pot, put your finger on the hole in the lid and the water will stop flowing. Release the fingers covering the pores and the water will flow back. Because there is a pressure difference inside and outside the teapot, the water pressure in the teapot decreases, and the water in the teapot no longer flows out.
