Legend has it that one night in more than 800 years, Emperor Huizong of the Song Dynasty read a large number of sonatas, and suddenly felt extremely tired, and went to the Moon Palace in a dazed mind. Between trance, he actually stood in the "Guanghan Qing vacuity house" plaque, everywhere strange flowers and herbs, incense wreathed. In the midst of wonder and hesitation, a pleasant flute was heard not far away. He loved poetry and songs, followed the flute actually saw the Chang 'e who was missing Houyi, in the moon palace that was a little cold but seemed to be real and unreal, all the fairies danced and long sleeves flew. At the end of a Ququ, the moon palace had been deserted for a long time because the arrival of Emperor Huizong of the Song Dynasty made the Chang 'e fairy extremely excited and was warmly invited to taste immortal tea. On the tea table carved into a thousand years of cold jade, placed a dazzling jianzhan, or smooth rabbit hair, or bright partridge spots, or bright stars like obsidian. Emperor Huizong of the Song Dynasty, admiring Chang 'e's skillful tea making, could not say a word. In order to alleviate this slightly awkward atmosphere, Chang 'e fairy told the origin of these jianzhan: "On the day of the Queen Mother's birthday banquet, the little jade rabbit stole the nectar and jade liquid, and fell into the world drunk, and fell to the side of the dragon kiln in the village of Shuijihoujing in Jianyang, dying." After being rescued by a kiln worker's father and daughter, the kiln woman carefully cared for more than a month, the jade rabbit in the middle of the night in order to repay the kiln woman for saving her life, took her body and nipped the black porcelain cup of the kiln. After the jade rabbit was injured, the kiln woman sent a lot of jianzhan to the little Jade rabbit and brought it back to the Moon Palace." Later, Song Huizong woke up from a dream, and the Xiantea in the jianzhan entrance left him unfulfilled, so he immediately gathered his troops and rushed to ShuijiHoujing Village overnight, not only brought back countless valuable jianzhan, but also sealed the dragon kiln as a "imperial kiln" for himself to fire jianzhan.
