Who is written in Xu Fengnian's notes?

Xu Fengnian heard an important news on his way to Wudi City, when Wang Xianzhi appeared in the capital and his mother was besieged. So Wang Xianzhi should know who the murderer is. He wants to find out the truth about his mother's death from Wang Xianzhi, but obviously Wang Xianzhi doesn't want to care too much, so what he said is also very vague.

Can't Xu Fengnian can only write a note to Wang Xianzhi to confirm, Wang Xianzhi personally admitted that this person was in Beijing, the name written on the note is actually Diao Han Temple. This man is a thug of Yang's royal family, and his actions show that his death was inspired by Yang's royal family.

Follow-up story:

Xu Fengnian, who learned the truth about his mother's death, on the one hand went back to the northland for a pretence, on the other hand, he carefully studied Deng Taiya's flying sword array and stopped on the only way for Diao Han Temple and others to go to West Shu, ready to avenge his mother.

In normal times, Xu Fengnian can't kill Han Diao Temple, but his flying sword array is used to deal with Wang Xianzhi. Killing Han Diao Temple is a natural thing. The evil eunuch also went offline with the end of the plot. In fact, although he is bad, he is really good to Zhao Kai. He is very kind.
