What does the Big Dipper have to do with seasons?

The bucket handle orientation of the Big Dipper corresponds to the seasons, and different seasons have different orientations. Bucket handle in spring refers to the east, bucket handle in summer, bucket handle in autumn refers to the west, and bucket handle in winter refers to the north.

The Big Dipper appears in different directions in the sky in different seasons and at different times at night, so the ancients decided the seasons according to the direction pointed out by bucket handle when he fainted for the first time:

Bucket handle, the Big Dipper, points to the east, and the world is spring; Bucket handle's guide to the Big Dipper, the world is summer; Beidou bucket handle points to the west, and the world is autumn; Bucket handle, the Big Dipper, points to the north, and it's winter in the world.

Other functions of the Big Dipper

Often called the Big Dipper, it refers to the seven very bright stars in Ursa Major in the northern sky. Seven stars are arranged in the sky like a spoon, so it is also called Beidou. They indicate the direction of the north.

Not far from the head of the Big Dipper, at the tail of Ursa minor, there is a star whose brightness is very similar to that of the Big Dipper. It hangs high in the northern sky. It is the North Star. Polaris is the most reliable sign that people can tell the direction at night. Every night, the stars will move from east to west (in fact, our earth rotates from west to east), but Polaris will stay where it is. This is because Polaris is located at the northern end of the earth's rotation axis, just above the north pole of the earth.
