What constellations are there in the winter sky? What's the approximate number?

Although it is very cold in winter, the starry sky is extremely magnificent.

Orion is the center of the winter sky. At the latitude of Xiamen, you can see three bright stars arranged neatly at night, which is what the folks call "three stars shining high". There are four bright stars around Samsung that form a rectangle with Samsung. This is Orion. Samsung is Orion's belt.

When the connection of Samsung extends to the lower left, you will meet the brightest star in the whole day: Sirius, which is the main star of Canis Canis. Extending from Samsung to the upper right is the bright red star Bi Su Wu. Next to it is Capella.

Taurus is Gemini in the southeast, Cancer in the east and lion head in the east.

To the southwest of Orion is the long and big but very dim constellation Bojiang. Only in Guangdong can we vaguely see the southern part of Orion is the sky map and Tian Ge, and the southern part is the main star of Carina.

Below Orion's Samsung, there is a bright spot, which is the Orion Nebula. Next to the leftmost part of Samsung is the Horsehead Nebula. The Pleiades cluster in Taurus is an excellent open cluster, consisting of about 500 stars.
