The distance from the bottom of the upper hook to the handle ring of the lower hook is also a single hook.
Bait; I usually use the easily atomized bait: North and South crucian carp or Dong Jun crucian carp, and add some silver carp and bighead carp essence (the ratio is 9: 1) or other commercial silver carp and bighead carp bait (the ratio is 2: 1) to find a fishing spot with a water depth of about 2 meters (without windward) without making a nest. Note: (Bait size: Generally, the bait is about the size of a big peanut or a little finger. When the water is deep, rub the bait twice more and let it slowly atomize. Each time you adjust the depth, you can adjust a float up and down. For large floats above No.6, adjust 8- 10 to catch 1-3 mesh). However, homemade acid bait can also lure fish at fixed points.
If you use throwing rod, big floating ball and acid bait. That is, monsters that use explosive hooks or specialize in fishing silver carp and bighead carp. The teacher on the second floor said it was a local monster, and it was also very easy to use.
