Is Sanyuan in the Milky Way?

The main constellations that the Milky Way galaxy passes through are Cygnus, Eagle, Fox, Sagittarius, Ophiuchus, Shield, Sagittarius, Scorpio, Rectangular, Wolf, Southern Triangle, Compass, Fly, Southern Cross, Vela, Tail, Unicorn, Orion, Taurus, Gemini and Auriga. Sanyuan, namely Ziweiyuan, Taiweiyuan and Tianshiyuan, is one of the star officials who divided the starry sky in ancient China, and together with the twenty-eight in the zodiac, they are called ternary twenty-eight. Among them, Ziweiyuan mainly includes the celestial sphere near the North Celestial Pole, which is roughly equivalent to the constellation Gongji, and is roughly equivalent to the internationally commonly used constellations of Ursa minor, Ursa major, Draco, Hound, Mu Fu, Unbounded Constellation, Wang Xianxing, Hou Xian, Yingxian and Lubao. Taiwei Courtyard contains some constellations such as Maiden, Houfa and Lion. Tianshi source includes snake man, five immortals, giant snake, skyhawk and other constellations. In this way, the main part of Ziweiyuan is not in the Milky Way, so on one side, Taiweiyuan is also on the other side, and Tianshiyuan has more parts in the Milky Way.
