When you face something, the behavior you would do according to your past personality and logic is destiny; if when something happens, your behavior is not in line with your past character and habits, and there is a big deviation, this is called luck; the behavior you habitually do without any external force is destiny, and the behavior you do against your character after thinking about it is luck. Therefore, it is said that luck is a change, and destiny is a destiny. The so-called changing destiny against heaven is not against heaven, but one's own instinct.
