What does Orion mean in summer?

In summer, you can see Orion, Leo, puppy, Big Dipper and Polaris. Look for three stars side by side in the sky. He is Orion's belt. Of the three, the upper one is the shoulder, and the lower one is the knee (opposite to the upper one). After seeing Orion, there are two vertical stars not far away, one bright and one dark, which is the dog seat. To the south of Orion is the Big Dipper, which is a big spoon. A little farther from the spoon, there is a very bright Polaris. Orion is in the north, the dog is in the west, and it is Leo.
