How can I find out which one is Sirius in the night sky?

Sirius is a member of the winter sky, at least in our lifetime. After watching Orion in winter, looking down at the lower left corner of Orion, you can see a super bright star, Sirius. In summer, it comes out during the day and is submerged in the brilliance of the sun. Moreover, Sirius has a low latitude and can be seen in both hemispheres.

It is invisible to the naked eye.
