There is a bright star near Orion recently. What is this?

According to what you said, I think it might be Sirius.

The main scene of the starry sky in winter night is a triangle formed by Sirius in Canis Canis, Nanhe San in Canis and Betelgeuse in Orion. The triangle formed by these three stars is located at the equator of the celestial sphere and can be seen all over the world.

Sirius is the brightest star in the night sky, with an apparent magnitude of-1.47, almost twice that of the second brightest star, Laonian. Its English name is Sirius, and its pronunciation is/? Is it? S/, from the ancient Greek σ ε? ριο? . Sirius was named alpha dog according to Bayer nomenclature [1]? .
