This statement has different understandings in different times. In the past, everyone believed in myths, so when they met something, they mainly sought the help of the gods. So many temples are consecrated by people, and there are many believers as propaganda. There is even a special Kannonji for many people to worship. But in fact, this statement is not very credible, and it is even a bit ridiculous in today's scientific community.
Because through the most official explanation, no one will give you your child, but you need to adjust your body in a scientific way. Although some people still believe that many physical things should adhere to science. Correctly adjust physical problems and get pregnant through some means. This method is still very useful, because many things can be explained by science now.
So this way of seeking children is still quite useless. The most important thing to have a baby is to face up to your physical problems. Moreover, although many people think that they really have children, it is also a reflection of your body, and the probability is very small. So don't toss about easily, it is most useful to find an authoritative hospital.
