Seek the detailed allusions of Mangshan and Mangshan in the north.

According to legend, in 520 BC, Lao Zi left the collection room of Zhouwangcheng and quietly went to Cuiyunfeng, the top of Beimang Mountain, and built the Altay Red Bagua Furnace all night to mobilize the spirituality of heaven, earth, water, fire, thunder, mountains, wind and ze in all directions. When the stove was turned on, with a loud noise, I saw thousands of golden lights shining directly into the sky. I tasted one myself, and suddenly my face turned purple, but I took off all my bones. So, Lao Tzu dipped his green cow with elixir, rode on the back of the cow, and went far to Mangshan Mountain in the north to "travel to Tianzhu to educate the conference semifinals".

Lv Dongbin

Lv Dongbin, the Eight Immortals, likes to visit the Central Plains. One day, Luoyang was found to be infested with plague, and the whole city was dead. He thought peony roots could drive away the epidemic. In order to save people's livelihood, he rushed to heaven to meet the heavenly queen, hoping to ask fairy peony around him to come down and save people. The Queen Mother of the West said, "What for heaven? Is it wrong to hit Miss Peony? If you go down to earth privately, you will be condemned by heaven. " Fairy peony was moved by Lv Dongbin's sincerity. He sneaked out of the Heavenly Palace and planted peony seeds in Beimang Mountain. When the Queen Mother knew about it, she was banished to earth to plant peony. Because the land in Beimang Mountain is fertile, and it always turns into a gentle breeze and drizzle, the peony seeds sown that night began to sprout and bloom. Lv Dongbin was very grateful for the kindness of the Peony Fairy, so he opened a teahouse on the official road of Beimangshan Mountain. Before long, the peony root was boiled and taken, and the plague was completely eliminated. To thank the fairy peony, people renamed Beimang Mountain "Peony Mountain" and built a Lvzu Temple in the teahouse to commemorate the immortal Lv Dongbin.
