What does East of Eden mean?

The title of East of the Garden of Eden has profound implications, which can also be said to be a metaphor of the whole play. To the east of the Garden of Eden is Midian, where Adam and Eve lived after being driven out by God. Midian is as rich as honey, and the children of Adam and Eve live a happy life. It was not until Cain killed his brother Abel out of jealousy that mankind committed the original sin of killing. This is the beginning of all misfortune. Shen Taihuan killed Dong Zhe's father, which was the unfortunate beginning of all the characters in the play. KY knew his sin well and said to God, Anyone who sees me will kill me. Dong Zhe's family always wanted Shen Taihuan to pay for his living expenses. God gave KY a sign. The person who killed you after seeing this sign must be seven times heavier than the crime you committed! Xu Dong is the son of Li Qizhe since he was a child, and it is his belief to bring Shen Taihuan to justice. Mingxun hurt his relatives without knowing it. Dong Zhe loves Xu Dong like a father. Even if the truth comes out, what about feelings and beliefs in the face of the mark given by God? KY left Midian, and everyone who wanders in this world is just like KY because of hatred and pain. Loneliness and sadness; Love without longing for love without loving. Wandering outside Midian, God forgave KY, but KY couldn't erase his sin. Even if we shed blood and tears in our hearts because of love, it can't change our desire for love and happiness. We will not return to the Garden of Eden, but at least we will find and own our own East Garden of Eden.
