If the fortune teller says that this person and I can be suitable, but the child born is weak, it will not improve my life, and I can't be faithful to my life.

Please don't believe these superstitious things. A person's destiny is to struggle on his own, and there will be no pie in the sky. Besides, his marriage is to run by himself, and fortune-telling is appropriate. It's futile for you not to struggle by yourself. Therefore, if you believe in your own destiny, you must work hard and control your own destiny. As long as you are self-motivated, work hard, be kind to others and have a sense of responsibility, you will definitely build a happy and harmonious family and work hard on your own.
