Eating mackerel represents a cultural symbol with profound meaning. In Chinese culture, the mackerel symbolizes good fortune and good luck. This is because the word "鲲" is homophonic with the word "bai", which means it means New Year's greetings and sacrifices. During the Chinese New Year, many families will prepare a mackerel to worship their ancestors and pray to gods and Buddhas. Not only that, in traditional Chinese weddings, the bride’s family will also use a mackerel to represent the bride and give it to the elders of the groom’s family after the wedding, which means that the two families will get together and wish the newlyweds a happy marriage.

In addition, mackerel is also a very important ingredient in Southeast Asia and Japan. The meat of Spanish mackerel is delicious and delicate in taste. It is rich in a variety of beneficial nutrients, especially Omega-3 fatty acids, which are very beneficial to human health. Therefore, Bayu is very popular among consumers. In Japan, mackerel is known as "one of the five major sushi dishes" and is often used as one of the main ingredients of sushi. In Fujian, China, there is also its own special mackerel delicacy - Fujian mackerel fruit.

In addition, there is another saying about eating Bayu, that is, "If you eat Bayu, you will have good luck year after year." This saying stems from the symbolic meaning of the Bayu fish in Chinese culture, which means that eating the Bayu fish can bring wealth and prosperity. Therefore, many people use Bayu to attract wealth and good luck during the Chinese New Year, hoping for better luck and harvest in the new year. Of course, during this process, people also need to pay attention to a reasonable diet and avoid excessive consumption to avoid negative effects on the body.
