What kind of feelings does the poem Qingming express?

In Tomb-Sweeping Day, it is a tradition to go hiking, worship ancestors and sweep graves with relatives and friends. The "pedestrian" in the poem is a person's journey in a foreign land, and his feelings are very lonely and desolate. Coupled with the continuous spring rain, "pedestrians" are inexplicably agitated and depressed, and their emotions seem unsustainable. However, "pedestrians" are unwilling to indulge in loneliness and sadness, and quickly ask where there is a place to drink, so as to be in the heat flow of people and wine. Then, the shepherd boy in the spring rain pointed to a piece of apricot forest in the distance. The end of the poem makes people feel far away, poetic and fresh and lively.
