How did the most legendary Lv Dongbin of the Eight Immortals last forever?

Lv Dongbin visited Lushan Mountain, met a real dragon, and taught Heaven to avoid swords and exorcise demons. In Huichang, he won the Scholar Award twice. At the age of 64, he was still in Chang 'an. When I first met Li Zhong, I was influenced by "Huang Liangmeng" and passed the "Ten Tests" test, and I got the Golden Liquid and the "Lingbao Dafa". I vowed to devote myself to monasticism and do my best for all beings in the world. When I first lived in Zhong Nanshan, Li Zhong taught me the truth and I became a Taoist.

Extended data:

At the age of sixty-four, Lv Dongbin visited Chang 'an and met a feather man dressed in Tsing Yi in a restaurant. This Mr. Fang Yun is Zhong Liquan. In the evening, Zhong Liquan and Lv Dongbin stay in the bar together. When Lv Dongbin was asleep, Mr. Fang Yun cooked for him alone. He dreamed that he was the top scholar, proud of officialdom, and full of children and grandchildren, which was extremely glorious.

Suddenly, he was convicted of a felony, his family property was confiscated, and his wife and children were separated. When he was old, he knew all this. He was down and out, standing alone in the snow shivering, almost sighing. Suddenly, Zhong Liquan's rice was not ripe, so Lv Dongbin made up his mind to learn Taoism from Zhong Liquan. After the test of "Ten Tests", Zhong Liquan passed Taoism on to him.
