Why did Di Renjie, Wu Zetian's right-hand man, become a detective?

I believe that the name of Di Renjie is well known to all of us. In recent years, there have been many movies about him, most of which are about how detectives Di Renjie and Di Renjie solve the case step by step, but in fact, the real Di Renjie doesn't know how to solve the case. He was a famous figure in the period of Wu Zetian. So, how did Di Renjie become a detective? ?

Di Renjie was born into an official family and entered the official career at the age of 26. He was falsely accused because of his honest and frank character. At this time, Yan discovered what had happened through investigation. At the same time, he found that Di was a talented person, so he recommended Di to join the army and take part in military exercises. Later, he was promoted to Dali Temple Cheng, responsible for large and small cases in Beijing. This is very effective. Di Renjie adjudicated a large number of backlog cases in one year, involving 17000 people, but no one complained unfairly.

Perhaps because of this, Di Renjie will be regarded as a detective by later generations. After Wu Zetian proclaimed himself emperor, she began to reuse Di Renjie and Di Renjie as prime ministers. Later, Emperor advised Wu Zetian to restore Li's orthodoxy. Finally, Wu Zetian agreed.

When De Renjie was an official, he was honest, not afraid of power, and had good governance everywhere. Therefore, people love Di Renjie very much. In order to praise Di, later generations in the early Qing Dynasty wrote a book "Four Mysteries of Wu Zetian", in which Di was the protagonist, but many stories in the book were fabricated. Later, as the book became more and more popular, a Dutch diplomat named Gao Luopei continued to collect cold cases about Di Renjie. He wrote a series of stories, collectively called "The Story of Judge De Solving the Case".
