+
+## Instructions
+
+- Clean the carp and make cuts on its body (several incisions help the flavors penetrate)
+- Wash the baby cabbage and place it in a plate for later use
+- Heat cooking oil in a pot. Add a pinch of "salt", "ginger", "garlic", "Pixian broad bean paste", "cinnamon stick", and "star anise", and stir-fry until fragrant
+- Place the fish in the pot and pan-fry (for 3 minutes, flip every 30 seconds)
+- Add "water" (the water level should be nearly even with the fish, slightly less is fine). Add "light soy sauce", "dark soy sauce", and "baby cabbage"
+- Simmer on high heat for 15-20 minutes. When the sauce is almost dry, add "salt" and serve
+
+## Additional Notes
+
+- You can also add some vermicelli noodles. Soak the noodles in cold or warm water until soft, then add them together with the baby cabbage.
