Du Fu, a poet in the Tang Dynasty, wrote the poem "Spend the Third Year in Fresh Weather" twice.

Du Fu's "Two Poems on the Road" in the Tang Dynasty: In the third grade, the weather is sunny, and the beauty is like a cloud by the Chang 'an River.

"On the third day of March, it was a sunny day, and many beautiful women were walking along the Chang 'an River." Since ancient times, March 3rd has been a day for spring outing. People have been drinking water by the water, which has become a festival and custom since the Han Dynasty. The opening of Han and Tang Dynasties was far from the opening of Song and Ming Dynasties. At least women don't have to bind their feet. The folk customs in the Han and Tang Dynasties were vigorous. Women should bask in the sun, and they should come out to play. They don't have to be locked at home in the future, and there are all kinds of mental shackles. In the Tang Dynasty, men and women relatively equal. These wealthy women also went out of Chang 'an to Qujiang for a happy spring outing.

Among them, the "March 3" in the poem is the festival of thinking. In the Tang Dynasty, more Chang 'an women and men visited Qujiang in the south of the city on this day.
