On the one hand, they are close to the sea. After all, China has a tradition of "relying on mountains to eat mountains and relying on the sea to eat the sea", where they can taste all kinds of delicious seafood. And because I have been at the seaside for a long time, I have been exposed to this kind of seafood since I was a child, and I have explored different ways to eat it. I will not get tired of eating seafood for a long time.

On the other hand, it is a habit of theirs. After all, many people at the seaside often fish and catch some seafood for sale. For those seafood that can't be sold, they are reluctant to throw it away and can only eat it themselves. And you don't have to go out to buy other food, on the one hand, you can save money, on the other hand, you can fill your stomach, and seafood is not so greasy, unlike pork, chickens and ducks.

The last aspect is their traditional customs. After all, they have many seaside customs, all of which are inseparable from seafood.
