What is the brightest constellation in the winter sky?

The starry sky in winter is the most magnificent all year round. Of course, the most striking thing is Orion in the southern sky. Along the Orion belt with three stars (Orion D, E and Z), you can see Sirius (Canis Canis A), the brightest star in the whole day. Just east of Betelgeuse (Orion A), there is a bright star of 1, Nanhesan (Canis Canis A). Betelgeuse, Sirius and the South River form the winter triangle, and the faint milky way passes through it, which is the darkest all day. There is a famous Pleiades cluster in the northwest of Orion, surrounded by the bright star 1 (Taurus A). Looking northwest, you can see the Pleiades cluster. The northeast of Taurus is the pentagonal constellation Auriga, and the brightest star Capella is 1. The northeast of Orion is Gemini, and the brightest star Kitagawa III (Gemini B) is also 1. Capella, Beihe III, Nanhe III, Sirius, Betelgeuse and Betelgeuse form the winter hexagon.
