What kind of emotion does the poet express through the swallow in the poem "Welcome to the Swallow"

Swallows nest under the eaves from autumn to spring. People regard them as mascots. "Ordinary people's home" refers to Liu Yuxi's "Lao Wang Xie Yan, flying into ordinary people's home" precisely because swallows don't care too much about poverty and love wealth, and go with the flow. The host also "does not abandon the old curtain" and warmly welcomes the swallows back. The phrase "the nest grows into a chick and grows with the chick" makes the swallow a part of life.

Swallows in ancient poems often symbolize a happy life. They fly together, and the swallow in this poem lives happily under the owner's eaves. The freedom of swallows is a portrayal of the poet's seclusion; The happiness of the swallow shows the happiness of the poet. Poetry vividly depicts the life habits of swallows and expresses the deep friendship between swallows and ordinary people.
