Zhouzhi county Louguan Town Louguantai alchemy peak on the left side of Wenxian ditch. According to folklore, there is a cave in Mizoguchi, where Lv Dongbin practiced in the Eight Immortals. One day, Lv Zu and his son came back from a banquet in Tianxian Palace. On the way, I met the bodhi old zu of Huashan Chen Tuan and the magistrate of Huayin to visit the building. The two immortals were very happy when they met. When talking about the language of supernatural wonderland, the magistrate can't understand the secret. At this time, Lv Zu took out three dates from the flat peach meeting, two red dates and one green date, which were eaten by two red immortals. The green jujube was given to the magistrate, who was very unhappy. He refused to give the date to his parents, but gave it to the boy. Afterwards, Chen Tuan asked the magistrate, do you know the owner's surname? He replied that he didn't know, so he told the judge that Lu Zudong was also a member of the Eight Immortals. The magistrate suddenly woke up like a dream and hurried along the ditch, unable to catch up with Lv Zu. He asked the immortals in the ditch, which was called Xianxiangou.
