I'm new here. A poor pole, six floats, how many floats are there on the water? How to see if the rain bites?

There are usually 7 pieces, which is the so-called "Seven Stars Gone with the Wind". Now this fishing method is only used in some wild ponds with many weeds. Personally, I think three pieces under water and four pieces above water are more suitable for fishing. If it is a delivery, three pieces are more obvious. If they are floating, I think two of them are floating underwater.
