Should we believe in so-called "fortune telling" and "birthdays"?

As for the date of birth, it is the year, month, day and heavenly stems and earthly branches, which is inherent to everyone. Believe it or not, he really exists. Fortune telling is based on the five elements to which heavenly stems and earthly branches belongs, believe it or not. People don't believe what they don't know and haven't been tested by practice, otherwise you will easily lose or miss the knowledge or people who are useful to you.
