What number hook and line do you use to catch rice crucian carp in winter?

Personally, I think Itsuno. 1 or Golden Sleeve No.3 is the most suitable. For the secondary line, it is about 0.4 to 0.6, and for the main line, it is about 0.8 to 1.0. If it is traditional fishing, it is better to use a line of 0.8. Last time I saw someone hook and throw an earthworm with a sea pole, and the hook rate was extremely high, so the hook and line he used were relatively large.
