Food: as simple and varied as possible. In order to avoid the tediousness of heating, it is appropriate to focus on cold food. For example, sandwiches, sushi, salads, ham, lavender fish, salted duck, tea eggs, dried tofu in marinade, homemade kimchi, etc., are both portable and delicious picnic food. Of course, if the theme is barbecue, meat and fish will be the main focus. Drinks:Canned drinks are the most convenient, but if you chill the lemon juice and put it in a thermos for your friends to drink, it will have an unexpected good effect.

Containers: It's best to bring plastic baskets with lids or rattan and bamboo baskets as food baskets; if it's a beach picnic, be sure to wrap them in plastic wrap and put them in well-sealed containers to prevent sand intrusion. Drinking cups should be disposable paper cups or clear plastic cups. Brightly colored and unbreakable plastic products are the preferred containers for picnics.
