模仿文本：I did some research into this. These incidences occurred fairly frequently about 40 years ago in Japan. And having researched into them, they always ended up choosing the child who's related by blood instead of the children they nurtured. So, yes I have actually based it on some real incidents and some case studies.

 

译文：对此我做了点研究。在40年前的日本，抱错孩子的机率相当高。研究后，我发现，他们最后总会选择有血缘关系的孩子，而不是养子。所以说，是的，这部电影确实是基于一些真实事件和案例的。
