What is the best line group for traditional fishing?

My line groups are all made by myself. Generally, the main line 1.0MM and the secondary line 0.6 mm are used for fishing wild crucian carp. In winter, this line group is relatively small, with the main line 0.8MM and the secondary line 0.4 mm. If earthworms are used as bait, Haixi No.3 barbed hook is used, if powder bait is used, non-barbed hook is used, and 0.3 new Kanto and 0. 1 new Kanto are used in spring, summer and autumn.
