In the fresh weather, many beautiful women are walking along the Chang 'an River.

This sentence is bright and colorful, and its style is exquisite and vivid, which satirizes the arrogant and extravagant life of Yang's brothers and sisters.

At the beginning, it is clear that "March 3 is crisp and beautiful, and there are many beauties by Chang 'an Waterfront" comes from Du Fu's poem "Two Roads" in the Tang Dynasty. In this poem, Du Fu describes a spring outing on the third day of March. On this day, the weather was fresh and the spring breeze was warm. Many Chang 'an people gathered in Qujiang to celebrate Shangsi Festival.

Why did Du Fu write down the specific time of March 3rd in his poems? Is there any special sense of ceremony for the spring outing on March 3? This has to start from the beginning.

It turns out that March 3 is an ancient festival, also called Shangsi Festival, and it is one of the traditional festivals in ancient China. Before the Han Dynasty, this festival was designated as the fourth day of early March. In ancient times, it was marked by "dry branches", and the first day of March to the fourth day of March was called "thinking". Later, it was fixed on the third day of March in the summer calendar.

Shangsi Festival has a long history. In ancient times, Shangsi Festival has become a large-scale folk festival. In spring and quiet time, people go out of their homes and gather at the water's edge to hold ceremonies to clear up the ominous. The word "Shangsi" first appeared in the documents of the early Han Dynasty. Zheng Xuan noted in "Zhou Li": "Except for the old, this is like water in March."

Shangsi Festival is the most important festival in ancient times. "The Analects of Confucius": "People in late spring, spring clothing achievements, five or six top scholars, six or seven boys. Bathing is almost a deduction, and the wind is dancing and singing. " I wrote about the baby's situation at that time. The baby had to go to the water bank to wash away the dirt, and at the same time it took away the evil spirits from me, which was meaningful for prayer.
