Sweden is a very big country in Europe, and it can be divided into many different parts called "lands". There are 25 of these "lands" in Sweden, and they all have their own special characteristics.
For example, one of these lands is called "Skåne". It's in the south of Sweden, and it's known for its beautiful beaches and delicious food. Another land is called "Lapland", and it's way up in the north of Sweden. This land is covered in snow in the winter, and people there have to wear special clothes to stay warm.
Each land in Sweden has its own flag and coat of arms, which are special symbols that represent that land. These symbols are used on official documents and buildings, and they help people identify where they are in Sweden.
So, the lands of Sweden are like different parts of a big puzzle, and each one is unique and special in its own way.
