Hanguguan-the idiom story of Xuanzong's reform to Yuan Dynasty

After Li Longji, Emperor Xuanzong of the Tang Dynasty began to think about alchemy and the art of immortality. Many alchemists and Taoists offered Dan medicine, and the whole family was promoted. At that time, there was a soldier named Tian Tongxiu in Chen Jiali.

One morning, he said that he dreamed that the old gentleman met him in Fengdan Building in Hanguguan at night. Lao Tzu said that there was a peach symbol buried in the place where he wrote the scriptures. Whoever can get it will win the world.

Upon hearing this, Xuanzong immediately ordered Tian Tongxiu to take people to the Hangu Pass where Laozi wrote scriptures, dug three feet and dug out a peach symbol engraved with the word "wood", which was interpreted by all the ministers as 48. I said that I can bless Xuanzong to sit in the world for 48 years. Xuanzong was overjoyed and immediately changed the title of Kaiyuan to Tianbao, made Laozi Emperor Xuanyuan and changed Taolin County to Lingbao County.
