What TV series is Dong?

This is not from the TV series. Dong is a character in the case-solving of the Southern Song Dynasty.

Feng Menglong recorded in Sanyan and Liangpai that a hermaphrodite nun Dong had killed hundreds of widows, and was later reported by a rogue and sentenced to death. Dong usually likes to go to the widow's house. Every time, she always patiently teaches widows Buddhism and embroidery techniques and sleeps with them at night. But Dong is a hermaphrodite with two sets of reproductive organs.

At that time, the adults who tried the case felt that they could not keep such a demon man to continue to harm the world, so they were sentenced to beheading.
