串门 (chuàn mén): to call on sb; to drop in; to visit sb's home

When I have nothing to do on weekends, I like to drop by my neighbor's house to chat with them.

Yesterday afternoon, my mother suddenly came to my house to visit, and she even brought some homemade snacks.

After moving into the new neighborhood, I often visited Old Wang across the hall, and we became good friends.

During the Spring Festival, people like to visit relatives and friends' homes to exchange New Year greetings.
