Is the Big Dipper among the 28 stars?

Amitabha! The Big Dipper doesn't belong to any star, because in ancient China, with the Big Dipper as the core, it was divided into five houses, east, west, north, south, middle and middle. The other four areas are divided into four areas according to the astrological characteristics: Qinglong, Baihu, Suzaku and Xuanwu. Each region consists of seven stars. The Big Dipper is located in the Weizi Garden in the "Three Walls", symbolizing the imperial car that the emperor went out to ride. Hope to adopt, thank you!
