Who is Lv Chunyang referring to? What's the story?

Lv Dongbin, also known as Lv Chunyang, is said to be surnamed Li. In a certain year when the plague was prevalent, his two sons died one after another. He was very sad. He told his wife that he wanted to change his surname. Li Zi had eighteen sons. People say he should have eighteen sons, but now he can't save any, only two sons are left. Let's just call him Lu. Soon his wife died again, and he said sadly, "Since my ex-wife died, I will never get married again." . From then on, Lv Dongbin saw through the world of mortals, saying that "pure yang is not yin". It is said that in order to make him live forever, Han Zhongli sent Lishan's mother to open a shop to entertain him, let him sleep first, and then let him eat a pipe meal when he woke up, but Lv Dongbin had a pipe dream for eighteen years. He dreamed that he went to Beijing to take an exam and won the first prize in one fell swoop. He was immediately worshipped as a marshal of the military forces, and Gao Taiwei recruited him as a son-in-law and lived a rich life for several years. Lv Dongbin is very proud. He is full of infinite love for secular life. However, the good times did not last long. Suddenly, Cai Yuanji rebelled against the imperial court, and the emperor immediately sent him to conquer. After more than 300 days of life-and-death struggle, Wu Yuanji was finally defeated and captured alive and won. But he sympathized with Wu Yuanji and released Wu privately. When I got home, I found that my wife had committed adultery with others and was about to catch the adulterer. The imperial court issued an imperial edict that he collaborated with the enemy and put him in prison. At this time, his wife forced him to write a letter of divorce and left him. Soon, he was exiled to Salmonella Island. Under the escort of Xie Cha, he took his two children on a long journey. Later, they were released to a place called Yaxianzhuang, but a devil pushed his child off a stone and died alive. He was very angry and fought with the devil. The devil cut his neck with a sword and he woke up with a loud cry. From then on, Lv Dongbin despaired and devoted himself to monasticism.

There are many legends about Lv Dongbin. It is said that after he became an immortal, he took it as his duty to kill pests for the people, and repeatedly fought with the white-faced snake essence and yellow-faced python who made waves in Dongting Lake, and finally beheaded them. Later, Lv Dongbin found that fishermen near Dongting Lake blackmailed fishermen and became beggars. At the fish market, he boasted that he was a fairy and was willing to sell it to others. The fisherman knew about it and bought it by force. Lu Xian put a small porcelain jar on the ground and said, As long as you fill this small porcelain jar with money, I will sell it to you. The fisherman disagreed, picked up the purse and poured it inside. But it didn't help to pour dozens of bags of money, so the fisherman poured all the money at home and disappeared. Lu Xian gave all his money to the local fishermen, who knelt and kowtowed all over the street, shouting "Living Immortals". Lv Xian turned into a wisp of smoke from time to time and drifted away. ...

The exhibition hall is divided into two floors with a height of 15m. It consists of four gold pillars and eight eaves pillars respectively. The pavilion roof is covered with golden glazed tiles, which is a mixed structure of cement and wood, and rests on the top of the mountain with double eaves. The pavilion base faces south, covering an area of 125.44 square meters. There are cloisters on the left and right sides, each with a length of13.51010/0106. The pavilion base has two floors carved with Lu Xian clay sculptures. Lv Dongbin, a sage-like figure, is dressed in a cassock, treading on stormy waves, wearing a green snake sword on his waist, holding a wine gourd in Dongting, holding a glass in his left hand and Buddha dust in his right hand, and smiling at all sentient beings with an indescribable smile.
