The eagle was pecked by the eagle.

I played with eagles all my life, and finally I was pecked blind by them. From Journey to the West "Three Borrowing Banana Fans". The moral is: I was calculated by a familiar person in my most familiar field.

It's the same as shooting geese all day and being pecked by them. Now the metaphor is that people always make mistakes, and Ma always stumbles. Often used to refer to overconfidence, negligence, and making mistakes that should not be made.

After playing with eagles all my life, I was finally pecked blind by them.

Journey to the West on June 1st: "The monkey ... fell down and shouted: Hey! I have been hunting geese all year round, but now I am blinded by a gosling pigeon. "

Interpretation: the Monkey King saw it and regretted it. He said, "It's all my fault." After that, he sighed and stamped his foot and shouted, "Alas, I beat geese every year, but I didn't expect to be pecked by goslings in turn today." I can tell right from wrong with my eyes, but I didn't expect to see it today.
