Why can't you get married if the eight characters don't match?

It's just a coincidence. In fact, the key question is whether you believe in these things. If you believe your parents agree, your mind will also make a complete mistake. If you don't believe in their parents' feudal ideas, how can they influence you? Everything should be centered on fortune telling, so you can't live, let alone be a major event in life. But if you are a dutiful son and are afraid that your parents will be hurt, you can find another fortune teller to solve your doubts. If people want to live happily, everything will be smooth sailing. It's really impossible not to give up at both ends. Make any excuse to say that your girlfriend is from Wang Fu.
