Everything has tears and emotions. There is a kind of tear called "Glaze Tears", which has a name and a life. It has experienced thousands of degrees of heat and was forged in a kiln that never sees the sun. It was born in the fire, and the one drop left behind is the tear of Nirvana. Glaze tears bear the sweat and efforts of potters. The glaze tears also carry Jianzhan’s longing and affection for the kiln.
