Food: Try to be as simple and diverse as possible. In order to avoid the tedious heating, it is advisable to give priority to cold meals. Such as sandwiches, sushi, salads, ham, smoked fish, salted duck, tea eggs, marinated tofu, homemade pickles and so on. They are both portable and delicious picnic food. Of course, if the theme is barbecue, it's mainly meat and fish. Drinks: canned drinks are the most convenient, but if you put lemon juice in a thermos and let your friends have a drink, it will have unexpected good results.

Container: it is best to bring a covered plastic basket or rattan basket as a vegetable basket; If it is a picnic on the beach, be sure to wrap it with plastic wrap and put it in a sealed container to prevent sand from invading. Drink cups should be disposable paper cups or transparent plastic cups. Colorful and unbreakable plastic products are the first choice for picnics.
