Qinglong represents the East.
The white tiger represents the west.
Suzaku represents the south.
Xuanwu represents the north.
In the 28 constellations, the Black Dragon is the star of the East, and its seven parts-horn, health, bian, room, heart, tail and dustpan-are very dragon-shaped. As can be seen from their meanings, the horn is the horn of the dragon, the kang is the neck, the bian is the root of the neck, and the room is the arm, that's right.
The tomb faces the northwest, that is, sitting in the southeast should not be regarded as a dragon. Qinglong faces east. And you are facing the northwest.
