How does a master fisherman level the water to get a glimpse? Is the empty hook hanging, and the float is just level? Fishing with bait and exposed eyes?

You're right, but it's more accurate to adjust the drift with an empty hook ten centimeters from the bottom, because the fishing line also has weight. A glance at the water is not good unless you catch raw slobber fish and fast fish. When fishing normally, you should level the water surface, catch two eyes and catch three eyes, focusing on small mouth, upper mouth and slow slide (that is, gently and slowly falling). If it is black, it is a bigger fish. This bleaching method requires that the bait is light and sticky, which is suitable for fishing crucian carp. If it is rubbing bait, the fish's mouth may be slow. If there is mud at the bottom of the water, it will affect the eating of the hook, because fishing is too dull, and the double hook undercover gets stuck in the mud! If you don't understand, please ask.
