Facing the stars in the sky, how can we know their names and constellations?

Some people can report the names and constellations of some stars at once, which shows that they have considerable observation and familiarity with the starry sky. As long as you look at the stars more often, compare them with the star map, remember them properly, and master some formulas and methods for finding stars, you will soon be familiar with the splendid starry sky overhead and gradually become an expert. Novices can install a mobile planetarium or starwalk and other star map software on their mobile phones, pick up their mobile phones and aim at the stars, so they can easily know the names and constellations of the stars. In short, we should be diligent in observation and focus on practice and persistence. I wish you a happy stargazing!
