Is autumn picnic still suitable for cold salad?

The weather is very hot. The average temperature in autumn is lower than 10℃ and higher than 22℃, and the temperature between 10~22℃ is considered as a normal range and relatively warm. You can eat some cold salad to cool off the heat, and the refreshing taste can also increase your appetite. However, if the weather has turned cold, especially in some northern areas, the temperature is already low. It is recommended to choose some warm foods, such as hot soup and stew, to keep your body warm and comfortable.
