The fortune-teller said that all my pregnant girls in the past two years were girls. I wonder if it's true.

How can you believe this? There is no scientific basis at all. Now that medicine is so developed, you will know if you go to the hospital for examination when you are pregnant. Most fortune tellers are liars! Not credible. In fact, girls are not better. Boys will be more filial when they marry and forget their mothers. . . Far from it, I wish you all the best!
