Some people like the sea because it is vast, deep, calm and open-minded. This is also a manifestation of mentality.
As a background, it is generally a calm and wide picture. So I like the sea as the background, and I hope my life is open-minded, inclusive and peaceful, and I like the sea very much.
Moral of the sea: the sea means boundless space and broad tolerance. As the saying goes, "All rivers run into the sea with great tolerance". The ocean is not always calm, it will always be rough, so it can symbolize passion and struggle, and can also describe a person's life. One's life can't be smooth sailing. Like the sea, there are quiet periods and wave areas.
