Greeting the God of Wealth is an ancient custom of the Han nationality in China during the Spring Festival. According to Han folklore, the fifth day of the first month is a birthday, and this day is also considered as a festival. Therefore, after the first day of the first month, the next most important activity is to meet the god of wealth. On the night before God of Wealth's birthday, every household will hold a banquet to celebrate God of Wealth.

There are many folk sayings about why the fifth day became the birthday of the God of Wealth, but there are two main ones: one is that Cai Jing was rich in the Song Dynasty; The other is related to Wang Yuanbao. Wang Yuanbao, a native of Kaiyuan in the Tang Dynasty, was extremely rich and made a fortune by selling colored glasses.

Many living habits of Wang Yuanbao, such as worshipping the God of Wealth on the fifth day of the first month, had a great influence on people at that time, especially on the folk customs of later generations. The custom of welcoming the God of Wealth on the fifth day of the first month has been passed down to this day.
