We call this kind of person like "purple star surrounded by stars" Wei Zi's life. But the scope of the encirclement is large and small. Born at home is the head of the family, born in the country is the head of the family. Next to Ursa Major, Ursa minor consists of 28 stars of magnitude 6 or above, among which Alpha Ursa minor is the famous Polaris. Seven of them are brighter than four. Seven stars, α, δ, ε, ζ, β, γ, η (Chinese names Gou Chen I, Gou Chen II, Gou Chen III, Gou Chen IV, Di Xing, Prince and Gou Chen Zeng Jiu) are arranged in a bucket shape, which looks like the Big Dipper, but the brightness is weak. The alpha at the end of bucket handle is Polaris, which is about 1 from the north celestial pole. It is a triad and a variable star.
