What are the stories about Poseidon?

Poseidon's love brought him many magical children. His wife Hai Houxing gave birth to his son Tritton, who is half man and half fish. Demeter didn't like Poseidon's ambiguity about her. When he became a horse, Poseidon became a horse and continued to chase her. A good horse named Arrion is the crystallization of their love. This horse can talk, and it must be the first in all carriage races in Greece. Poseidon also took away the beautiful girl Delphi, took her to an island, turned her into a sheep and turned herself into a ram. Then, the ram with golden hair appeared.
