Eight characters can't determine the fate of a person's life. Eight characters belong to superstition. Don't believe it or not. One's life is not lived by eight characters, but by one's own efforts and struggles. Only through our own efforts can we live a better life. This is your own life. I am the master of my life. Don't believe in superstition, it's equivalent to eating until you die. This is also irresponsible to yourself.
Therefore, the eight characters are only a speculative method, which can not accurately describe a person's life, but a person's life needs to be realized and changed by his own efforts.
