Introduction to Lu Zu Palace: Lu Zu Palace is also known as Chunyang Cave. It is said that Lu Dongbin visited Langyuan and left a poem on melon skin. Before the poem, there is a preface from the Qing Dynasty: "Lu Xian visited the emperor here, and he used melon skin as a poem." Use a pen to make ink from melon juice, and recite poems on stone." Today, Guapi's poems are well preserved and can be explained orally by tourists, which is very interesting. There is a statue of Lu Zu in the temple, which vividly reflects his immortal posture. Next to it is a couplet: "I don't seek wealth and splendor, I only love the mountains, rivers and haze." It cleans the body and avoids disasters, and the words are very transcendent, which adds a bit of aura to the hall.
