Are all constellations made up?

No, I think constellations should be regarded as statistics ~ ~ are some special characteristics of specific people, classified into the same range, and then given a noun. Of course, it may also be because people have been exposed to constellations since they were very young, and then unconsciously approached their own constellations in the growth stage of their personality, and then grew up. These characteristics related to constellations will be obvious. Hehe ~ it's not 65438.
