This mainly depends on what flavor you prefer. The customs of the south and the north are different. The south prefers light tastes, which are basically original, such as ginger, onion and squid (which can keep fresh). If you don't put anything else, the north will be different. Mainly based on spices, such as fennel, cinnamon, star anise, pepper and so on. I like a light taste. The practice in the north feels that meat is the mainstay and the soup is not fresh.
