According to legend, during the Guangxu period, there was a shopkeeper named Zhou in the ancient city of Jimo who ran a cloth and silk shop named "Chun Xing Yong". On the night of July 2 1 day, he had three identical dreams in succession. In the dream, he clearly remembered that he was in charge of business. Suddenly, an old man with long hair appeared outside the door. As soon as I entered the door, I sat in the chair and said to him, "Tomorrow is my birthday. No one has given me a birthday anniversary for many years. Who will give it to me to ensure that his business is booming ... "Boss Zhou is a businessman. In order to get lucky, he prepared incense paper, offerings and firecrackers early the next morning. At the order of the old man in the dream, we set off firecrackers to pay homage to our ancestors ... Strange to say, many people came to watch the fun that day. After reading it, they all flocked to the store to cut and make silk, and the originally deserted business immediately flourished.

Shopkeeper Zhou's greetings were quickly spread by busybodies, so on July 22nd of the lunar calendar, all the shops in jimo city followed suit, which has been passed down to this day, forming the custom of greeting.
