Looking for Polaris, which constellation can you find first?

Ursa minor. Polaris is a famous star. Everyone wants to know it. Finding the North Star is to find the true north direction, which is not only useful for people who often work in the field, such as aviation, navigation, surveying and mapping, geological exploration, but also indispensable knowledge for us. How to use Ursa Major to find Polaris? First, find the outermost two stars of the Big Dipper, Shu Tian and Tian Xuan, and connect them with imaginary lines. Extend this place from Tian Xuan to Shu Tian about five times, and you will meet a bright star, namely the North Star. In that part of the sky, there is only one star as bright as Polaris, so it is easy to find. Facing the northern sky, you can see two famous constellations: Ursa Major and Cassiopeia. These two constellations are easy to recognize. Ursa major has seven bright stars: Shu Tian, Tian Xuan, Tianji, Tian Quan, Yuheng, Kaiyang and Yaoguang. They form the shape of a spoon. Some people call it the spoon star, which is generally called the Big Dipper. The five main bright stars in Cassiopeia form the phonetic letter W. These two constellations can help us find the North Star. Source: Reading and Composition (Senior Primary School Edition)
