How to understand the sentence "From now on, if you ride on the moon leisurely, knock on the door with a stick all night"?

From now on, if you ride leisurely on the moon, you will knock on the door all night with your cane:

In the future, if I can go out for a walk in the bright moonlight, I will definitely knock on your door at any time with a cane.

[Appreciation] The first triple wrote an external scene and incorporated his own feelings. But it seems that the poet's intention is not enough, so he changed his pen: "From now on, if you ride on the moon leisurely, you will knock on the door all night with a cane." Anytime, anytime. The poet has been swimming all day. At this time, the bright moon hangs high, and the whole earth is shrouded in faint clarity, which also gives the village after the Spring Festival a layer of quiet color and has a special taste. So these two words naturally flowed out of my chest: I hope to ride the moon with crutches from time to time, gently fly and have a cordial conversation with the old farmer. This situation is a great pleasure. The image of a poet who loves his hometown and is close to farmers is vividly on the paper.

[Background] This poem was written in the early spring of Song Xiaozong main road (1 167) three years ago, and Lu You was at home. Before that, Lu You was a judge of Longxing House (now Nanchang City, Jiangxi Province). In the second year of Longxing (1 164), he actively supported the anti-Jin general Zhang Jun's northern expedition. After Liv's defeat, she was excluded by imperialist lords and capitulationists, and was accused of "testifying, singing right and wrong, and urging Zhang Jun to fight". When Lu You returned to her hometown, her mood was quite complicated, and her anguish and resentment were intertwined, but she was not disheartened. The patriotic feelings of "generosity is still strong" (Yu Wen) made him feel hope and light in rural life, and poured this feeling into his poetry creation. This poem was written in my hometown of Yin Shan (now Shaoxing, Zhejiang).

[Author] Lu You

Don't laugh at the farmhouse music brewed in the muddled month. In the harvest month, the dishes for guests are very rich.

There is no way to go because of the winding water flow in the mountains, and a mountain village suddenly appears in the willow-green flower bay.

Xiao Gu followed the Spring Club and dressed simply and quaint.

In the future, if you can go out in the moonlight, I will knock on your door at any time with my cane.
