Different sales methods and different tastes.

1. Different sales methods: hot brine is made on site and sold in a heated state, while cold brine is cooled and then sold. The advantage of cold brine is that it has a complete range and can meet customers' needs for different tastes, but the taste of cold brine is not as good as hot brine.

2. Different tastes: Hot-braised meat will emit a rich meaty aroma during the heating process, while cold-braised meat is relatively cold and lacks rich taste.
