What does it mean to be sincere when you come to the door?

It means that there are few guests in the Menluo Courtyard, and those who come to visit need to be very sincere.

The house is indifferent: it is a Chinese word, which is interpreted as describing being very cold and having few guests.

From Bai Juyi's "Pipa Xing": "My younger brother left to join the army, and my aunt died. When I leave in the evening, my appearance is the same. There are few horses and saddles in front of the door, and the boss married a merchant's wife."

The visitor. Sincerity: People who come to visit need to be very sincere.

"Pipa Travel" is about the author who was demoted from Chang'an to Jiujiang and listened to a Chang'an old man playing the pipa and telling his life experience on the ship. As a long narrative poem, this poem has a rigorous and meticulous structure, well-proportioned, twists and turns, and ups and downs. By writing about the misfortune of the Pipa girl's life, combined with the poet's own blows in his official career, he sang the sentiment of "we are both fallen people in the world, so why should we meet before".

Social turmoil, the harshness of the world, sympathy for the fate of the unfortunate, and feelings about one's own frustration, all these painful feelings that were originally accumulated in the heart are poured into the poem. Its artistic success also lies in the use of beautiful, distinctive and musical language, and the use of visual images to express the feelings gained from hearing. The natural scenery and emotions of separation made by the bleak autumn wind make the work more touching.
