Why did Qi's poems make Su Dongpo laugh?

Su Dongpo joked with a friend: "It's easy to endure things in the world, but it's really hard to keep from laughing when reading Dr. Wang Qi's poems." Wang Qi's poem "Zhuzhi Fu" contains "leaves fall a thousand swords, wither ten thousand cannons", which is a masterpiece in his life. Please read Su Shi's. Su Shi looked at it and said, "Good is excellent. Just ten bamboo poles and one bamboo leaf. " When Wang Qi wrote these two poems, he only considered the hierarchy and antithesis, and forgot to calculate whether the ratio of bamboo poles to bamboo leaves was reasonable, which led to this joke.
