When will Ursa major be seen?

You can see it all year round, but the night in spring is the most eye-catching. In the north, it is mainly composed of seven bright stars, shaped like a spoon, just like an ancient vessel for holding wine, so it is called the Big Dipper, also known as the Big Dipper. Among them, four stars make up a bucket spoon, and three stars make up the bucket handle. The position of the Big Dipper in the northern sky is different in different seasons and at different times, so we can judge the seasons according to the position of the Big Dipper. China's ancient book "Goose Bird Tube" has: "bucket handle refers to the east, and the world is spring; Bucket handle guide, the world is summer; Bucket handle refers to the west, and the world is autumn; Bucket handle refers to the north, and it is winter in the world. " . At dusk in spring, the bucket handle of the Big Dipper points to the east.
