There are many versions of "Three Amethyst", the most popular version is the one published in the light years of the Qing Dynasty. In the process of inheritance, in order to adapt to the development of the times and people's needs, later generations revised and supplemented the original foundation, adding content about the Qing Dynasty and the Republic of China, making it more abundant and perfect. So what we are seeing now is not limited to the Song Dynasty, but covers a wider historical period.
