The sceneries written in the village evening are very unique. Please choose one to appreciate from the perspective of word refining, and tell us what kind of feelings the author expresses.

"Dawn in the Village" by Lei Zhen, a poet of the Song Dynasty, depicts a picture of a herdsman returning home with clear grass, a pond full of mountains, a setting sun on the mountain, a shepherd boy riding a bull, and a flute blowing. It expresses the author's relaxed and joyful thoughts, feelings and views. The yearning for a free village life. The word "horizontal" in the last two sentences expresses the shepherd boy's confidence in easily controlling the old cow and the leisurely riding on the back of the cow; the word "xin" expresses the shepherd boy's unconventionality and whim.

Original poem:

Dawn in the Village

Song Leizhen
