What does the fortune teller mean by "group"?

I would like to ask the fortune teller that children are a group.

Not credible. In the past, fortune telling was a superstition. People believe in the year, month, day and hour of birth and arrange them into eight characters according to heavenly stems and earthly branches, which is called eight characters. Then use this five elements to calculate people's fate and judge their good and bad luck. Not credible. Therefore, it is not credible for fortune tellers to say that children are a group.
