Apart from the spring breeze, what does Tu Su mean when she was sent to Tu Su at the age of one?

Tu Su, this is the name of a wine. In ancient China, people used to drink Tu Su wine on the first day of the first lunar month to avoid the plague.

With the firecrackers, the old year passed. People drink festive Tu Su wine and feel that spring is coming warmly. "Firecrackers are one year old, and the spring breeze warms Tu Su." Setting off fireworks on New Year's Day has been a custom since ancient times and continues to this day. It refers to the New Year wine made of grass or several herbs in ancient China. In ancient customs, every year on the first day of the first month, the whole family drank Tu Su wine, and then wrapped the dregs in red cloth and hung them on the doorframe to "exorcise evil spirits" and avoid the plague.

This poem is Yuan Ri written by Wang Anshi in Song Dynasty. The full text is: firecrackers are one year old, and the spring breeze enters Tu Su from send warm. The rising sun sheds light on doors of each household, New peachwood charm is put up to replace the old.

This poem eulogizes the birth of new things, and is as full of vitality as Spring Breeze Warming Up. It also contains profound philosophy, pointing out that new things always replace declining things.
