Wenchang.
Wenchang is an extremely intelligent person, with four pillars including a school or poetry hall, and his main focus is academic excellence. Huagai means unparalleled talent and extraordinary insights. It refers to a literary and artistic flavor, but it does not mean intelligence, so Wenchang is smarter.
The Huagai star is one of the star officials in Chinese astronomy. It belongs to Ziweiyuan and has sixteen stars. It is shaped like an umbrella. Ancient astrologers used the lower part of the triple union as the canopy.
