[Idiom story]

Zhao was going to crusade against Yan, and Su Daiyan went to persuade Zhao, saying, "When I came here, I saw a clam shell coming out of the water to bask in the sun. A snipe came to peck at its meat, and the mussels immediately closed and clamped the snipe's mouth. The snipe said, "If it doesn't rain today and tomorrow, there will be dead mussels." The mussel also said to the snipe,' If you can't open your mouth today, there will be dead snipes tomorrow. Neither of them would let go, and a fisherman caught them together. Now Zhao is going to attack Yan. If Yanzhao is at loggerheads for a long time, the people will be miserable. I'm worried that the powerful Qin will become a fisherman for nothing. So I hope your majesty will seriously consider sending troops. Zoe Wen Dao: "All right." So he stopped sending troops to attack Yan.
