Mother is a rooster, son is a tiger, born on March 9, 69, son is a tiger, born on March 8, 98, very disobedient.
Son, disobedience is normal, and it has nothing to do with some metaphysics.
If the old mother and the younger son ask you to give up one of your family ties because of the so-called mutual recognition of birth dates, can you do it? Be kind to every family member.
