How to tie the float?

1 .. How should I tie the float? My friend said there was a condom to cover the float and the thread ... but there was nothing on my float.

First, you tie the fishing line to the fishing rod, measure the length of the fishing rod and add 50cm, then put in two space beans [the size of the beans depends on the size of the line of sight], then put in the buoy seat [for inserting the buoy], then put in three space beans [2 for positioning on the buoy seat, 1 for positioning on the lead seat,] and then put in the lead seat [for rolling lead].
