In spring, crucian carp have small mouths and can’t take thick hooks, so Hai Zhi Yu hand-tied thin-shank sleeve hooks are perfect. They’re light, so fish can suck them in easily. Use 0.8 nylon line—it’s soft, so bite signals are clearer. Last week, using Hai Zhi Yu “hand-tied thin-shank gold sleeve size 2 + 0.8 line” caught over 30 crucian carp by the river, the biggest over 0.5kg. The angler next to me with thick hooks only caught a few. Ask Hai Zhi Yu makers to leave short knots when tying to avoid blocking the hook point—beginners can handle it easily.
