As a son, I am firmly opposed to celebrating my father’s 70th birthday. Am I wrong?

As a son, you have no right to decide whether to celebrate your father’s birthday or not. This is the basic filial piety. Even if your parents are at fault, as a child, you cannot repay even one ten thousandth of the kindness you have given in raising them, let alone fulfill your filial piety. Originally, it was filial piety on both sides, and you should do your best to make the old man happy, but you behave like this. Does your aunt want to see your parents unhappy? Although your parents can't see your aunt off, they don't have your aunt in their hearts. When you wish her a happy birthday, by the way: On this day of celebrating your father's birthday, I hope that your family can raise a glass to the aunt who once cared about us, and wish her a happy future. Way to go!
