Is Polaris Ursa major?

At night, there are two easily recognizable constellations in the northern sky, one is Ursa major and the other is Ursa minor. The constellation Ursa major is arranged like a water ladle in the northern sky, so it is also called the Big Dipper. Beidou refers to the Big Dipper, not a star. The arrangement of Ursa minor is similar to that of the Big Dipper, but the brightness is not as good as that of the Big Dipper. The last star on the barrel handle of Ursa minor is called Polaris.
