The main sources of cold salad are kelp, coriander, dried bean curd, and some meat dishes mainly including chicken, pork and beef. These materials are easy to buy in the market, and there is generally no big price gap, so these materials can be purchased in the local vegetable wholesale market. However, if you are engaged in the cold salad business for a long time, you can have a good relationship with a fixed supplier and strive to purchase goods from him for a long time.

Cold dishes are suitable for all seasons and all ages. If you eat cold dishes in summer, you can cool down and cool off the heat.
