Colluding idiom stories

The imperial examination system prevailed in the Tang Dynasty, and Cui Ling was an official in Tang Xizong. A large-scale imperial examination was held in Beijing, and many people came to participate. Cui Ling is the examiner, and one of the second interviews is Cui Ling, who is very talented. Cui Ling approved Cui Ling's paper and was impressed by his talent and appreciated it very much. On the day of the release of the list, Cui Yunbang was famous and admitted.

According to the rules at that time, the imperial examination and the people were "students" of the examiner. As a proté gé, Cui Ling had to pay a solemn visit to Cui Ling, the "mentor". What a coincidence! The examiner's name is Cui Ling and the pupil's name is Cui Ling. People who love to play put these two words together to become two sentences: "The primary and secondary school students are in cahoots." It was a joke, not derogatory. However, it was later heard that Cui Ling won a good official position soon after winning the lottery, which was questioned by others, suggesting that they were in collusion. Gradually, collusion changed from a joke to a derogatory idiom.
