In the spring of the fourth year of Xianfeng, Qing Dynasty, a Shunde native who lived in Qingyuan City and loved Feng Shui (commonly known as watching Feng Shui) was named (also known as Li Prajna). He is the founder of Lv Chunyang, and Lv Chunyang is a Taoist who dreams of Taoism at night. Dahekeng Banana Garden in the northern suburb of the county seat is a blessed land in Zhong Ling, a closed place in the Qing Dynasty, and a Taoist temple can be built in Xianyu to enlighten the world.

Therefore, Li Shouyi found a "Xanadu" according to his dream. According to legend, Li Shouyi came to Qingyuan with his father from Shunde daliang town to do silk business and lived in the east of the city. Because of his love for Feng Shui, he became a strange man.

Li Shouyi liked geography since he was a child, but he turned to it for help whenever he had the chance. When I was a teenager, I was able to recite the Tao Te Ching. In my early twenties, I learned the Book of Changes. When I was in my twenties, I became a Mr. Feng Shui, free of charge. In Fengcheng Lane, there is a saying that "Prajna looks like jade, sounds like silver, and Taoist children are reincarnated".

Li Shouyi dreamed that the day after the arrival of Lv Chunyang's father, he invited several fellow villagers to have an outing in the northern suburbs. The group finally came to Dahekeng Banana Garden. However, seeing the ups and downs of the mountains, the mountains are green and the waters are green, the two veins are distinct, and they circle around, the Woods are trimmed with bamboo, and the purple gas comes from the east. Li Shouyi and others couldn't help but be overjoyed and say, How clever our ancestors were! Banana Garden Gan Kun also.

After several investigations and inquiries, it was confirmed that this was a blessed land for the Qing army to retreat to. Therefore, in order to raise funds to build the Taoist Temple of the Immortal Pavilion here, the number of people who responded increased from 10 to 28, including,, Feng Juefen, Li Anyi, Huang Xifan, Chen Baifen, He Pengfei, Feng Xuanzhong, Feng and He Yuling. They asked the magistrate of a county and were allowed to raise funds to build it. In the winter of the same year, the Taoist temple was completed. This is the early "Taoyuan Fairy Hall".

When Xiange was completed, Jia, a businessman from Qingyuan, went to congratulate him. It was very lively. The county magistrate Cheng inscribed the word "Dahedong" to show the merit of building the Fairy Hall. Its name is taken from the place name Dahekeng, which means "harmony and auspiciousness".

Li Shou looked at it, pondered for a while and said, "It's too big!" So, I picked up the brush that Cheng Zhixian had just put down and touched it gently under the word "big". This "point" points out the essence of Taoism, the mystery of cave and land, and a century-old legendary "Taihe Ancient Cave". Later generations honored 28 people, including Li Shouyi, as "Twenty-eight Friends of Mountain Building" to commemorate their contribution to the establishment of Xiantang.
