The opening time on the seventh day is the best time to open the market on the tenth day.

The seventh and tenth days are auspicious days for the opening of the market. Good luck on the seventh and tenth day, good noon, start bad, end bad.

Opening the market is a traditional folk custom in China. During the Spring Festival, the opening day is the fifth day of the first month.

On the opening day, large and small stores will hold opening ceremonies. At the beginning of the day, the shopkeeper's first step is to burn the portrait of the god of wealth and then set off firecrackers at the door of the store. The waiter shook the abacus and knocked on the scale, and there was a noise inside and outside the house.

In a lively atmosphere, the man opened all the doors and windows of the shop, revealing the couplets that had already been posted and officially started business.

In Zhejiang and other places, there are five-color refreshments in the store on the opening day, and the first customer is called "God of Wealth". Zhenhai, Cixi and other places have the custom of welcoming eight guests, which is called "inviting eight immortals".
