How to tell the Gemini in the night sky?

Gemini is located between Taurus and Cancer, with Auriga and Tmall in the north and Sagittarius and Canis in the south. Auriga and the very humble Tmall are located in the north, while unicorns and Canis canis are located in the south.

Extending the connecting line between Orion's beta star and alpha star to the northeast, we can meet two bright stars which are not far apart, among which the brighter one is Gemini's beta star with brightness of 1. 14, etc. The dimmer star is Alpha Gemini with a brightness of 1.97. A series of stars τ, ε, μ starting from α star is almost parallel to another series of stars τ, ζ, γ starting from β star. They are imagined as two friendly brothers-casto and Poole Jocks.

Extended data:

To the west of Gemini is Taurus, and to the east is relatively dim Cancer. Auriga and the very humble Tmall are located in the north, while unicorns and Canis canis are located in the south. Gemini has two very bright stars-Beihe III and Beihe II. Other stars are dark, and only γ can be seen under city lights, but in places far away from light pollution, slender galaxies can be seen passing through the west of Gemini.

The winter hexagon consists of three rivers in the north, five rivers in Taurus, two rivers in Auriga, three rivers in the south of Canis, Sirius in Canis and Betelgeuse in Orion.
