Lei Kesheng's son's name is Lei Ming. Lei Kesheng has children and grandchildren. He is over 80 years old, not to mention his grandson. Even the great-grandson should have him. But Lei Kesheng doesn't even have grandchildren. In fact, all this is because of his son and daughter. Lei Kesheng's son and daughter have two incomes and no children, so they have no children. Every old man wants his children and grandchildren to wrap around his knees when he is old, but Lei Kesheng can't enjoy the happiness of children and grandchildren wrapping around his knees.
