At this point, some people may be asking, how do you exactly carry out these operations in practice?
It's complicated if you say it is, but also very simple if you say so; just hang the normal hook bait and find the bottom.
Pay attention to casting a full rod and a seven or eight part rod, and observe the depth changes reflected by the float. If the slope is too steep, it will be very easy to lose sight of the float. If the bottom is flat, then the water depth doesn't vary too much in all directions.
If you can't find a flat underwater structure, then you'll want to make your nest on these steep slopes at a closer range, which is what the older generation means when they say 'make the nest close, fish at a distance.' How close exactly should you make the nest depends on the slope's steepness, the water depth at which you're fishing, and the actual situation when you're making the nest.
