What's the principle of fishing in Taiwan Province now, and what's the difference between it and traditional fishing methods?

I remember fishing when I was a child. At that time, there were not so many brands of fishing rods. Generally speaking, bamboo sticks, reed sticks and wooden sticks are used. The line group is also very simple. The main line was directly tied with a single hook, put on a seven-star drift (the big feather on the goose wing I used at that time was cut into one centimeter), grabbed a lead pendant and started fishing. This may be the original traditional fishing, right?

If we say the difference between traditional fishing and Taiwan Province fishing, I think it is roughly two points: 1. Taiwan fishing makes buoy signals more sensitive by adjusting drift. 2. Protection of the line group. Because the Taiwan Province fishing line group has a secondary line, and the strength of the secondary line is lower than that of the main line, the main line will generally not be broken, so that the service life of the line group, the float and the fishing rod is longer.

As for the single hook and double hook, I won't say it.
