2, people wear coats, fish wear grass, and it is good to fish in the grass nest in winter. I'm afraid only crucian carp can eat in winter. Other fish have swam into the cold deep water. Except for crucian carp, which can fish all year round, crucian carp actually loves to drill grass in other seasons. It is said that fishing without grass is actually dead branches. In winter, even if it is not a grass nest, it is also a dead branch.
