One's fate cannot be altered. However, as each person's life course is matched up with the times of the universe, the interaction of yin and yang and the mutual generation and destruction among the five elements create different opportunities and variables, sometimes good, sometimes bad. This is called "fortune."
命不能變，但是每個人生命歷程與宇宙的時間對照配合時，因為陰陽五行的相生相剋，會有不同的機緣，有時好，有時壞，這就是運。
