How to find the constellation in the sky? Where's Leo?

You should be familiar with the main shapes of the constellation you are looking for and its neighboring constellations, and then know the approximate position of the constellation in the sky at the current time (the same constellation is in different positions at different times). Leo belongs to the zodiac and now appears in the East at night. Constellations around the North Pole can be seen all year round, and the Polaris is located at the top of the tail of Ursa minor.
