Constellation and direction _ Constellation direction Why is the west on the right?

The northern hemisphere looks at Polaris to tell the direction, so what constellation does the southern hemisphere look at to tell the direction?

Use the Southern Cross to determine the direction

The Southern Cross constellation, located near the southern celestial pole, is composed of four bright stars in the shape of a cross, which is called the cross star in China and is the main basis for determining the position in the southern hemisphere at night. In the area south of 23 north latitude, the Southern Cross constellations α and β are the famous first-class bright stars in the southern sky, and γ is the second-class bright star, so the connection between γ and α can extend along the direction from γ to α.
