It means that I have not been able to see the emperor for ten years (taking the imperial examination), so I believe that the saying that the world of mortals is delayed by fate is a lie.
“After ten years of not knowing the king’s face, I began to believe that Chan Juan misunderstood the person” comes from the Song Dynasty poet Ni Longfu’s “Palace Grudge”. The original text is:
The green sleeves are fragrant and the mirror is dusty, and a thin flower cannot hide the spring.
After ten years of not seeing the king, I finally believed that Chanjuan had misunderstood him.
The meaning of this poem is: The green sleeves have no fragrance, and the mirror is covered with dust. A thin and skinny flower cannot hide spring. (Take the imperial examination) I haven't been able to see the emperor for ten years, so I believe that fate in the world of mortals can help people who are lost to escape.
In ancient China, the biggest goal of literati was to take part in the imperial examination, win fame, and get a title on the gold list. Therefore, there is a saying that they have been in the cold window for ten years. On the way to take the imperial examination, they often have to give up many things, including love and marriage, because family will affect their study.
However, not everyone can be named on the gold list, and those who fail are often the vast majority. At this time, people who fail the ranking often begin to wake up, hate blindly pursuing fame and fortune, and begin to realize the value of love. Therefore, there is a saying that "I haven't seen the king for ten years, and then I believe that Chanjuan misunderstood the person".
Extended information:
"I haven't seen the king for ten years, and then I believe that Chanjuan misunderstood people" is a famous poem in ancient China. It is widely known because Wang Shifu, a dramatist of the Yuan Dynasty, quoted this sentence in "The Romance of the West Chamber".
In the play, Zhang Sheng, who was going to take the scientific examination, saw Zhang Yingying's beauty and said, "I haven't seen the king for ten years, but I believe that Chan Juan misunderstood people." It expresses his willingness to give up fame and fortune for love, giving this sentence a deeper thought and emotion.
