Picnic is an outdoor leisure activity. In Europe, it used to be a more formal royal social activity. When having a picnic, you need a spacious courtyard and a waiter to serve you.
Now, as long as you can easily take a multifunctional picnic bag and travel with friends or the whole family, you can walk into rural seashores, rural wheat fields, forests and lakes, parks and valleys, find food with nature and exchange feelings with friends and relatives.
