Swallows are joking in class.

Teacher Ji: Gege is entering school for the first time today. I want to see Gege's education and make further study plans. What does Gege think? Swallow thought: I did badly in the test. Teacher Ji: I wonder how Gege knew Du Fu and Li Bai. The swallow thinks: What tofu is white? What the hell is this? May: The swallow in the Tang Dynasty thought: What kind of sugar is fried with sugar? Fried chestnuts with sugar? Ertai: Poet, Swallow: Dead? Teacher Ji: I didn't catch what Gege said. would you please say that again. The swallow thought, it's definitely not fried with sugar. Terrible ... three seconds later, I knew it was fried stinky tofu. Teacher Ji: Fried stinky tofu? Swallow: Teacher Ji: Why is it fried stinky tofu? Swallow: This tofu is white inside, but it must not be white outside. This fried stinky tofu is yellow outside and white inside, so this fried stinky tofu is white inside. Emperor: This is the greatest and most wonderful teacher Ji Jie I have ever heard in my life: A Benmingjie, do you know Du Fu and Li Bai? Benjamin: Two poets in the Tang Dynasty. Li Bai's poems are bold and unconstrained, while Du Fu's poems are neat. Teacher Ji: Does Ben know Gege? Swallow glared at Benjamin Benjamin, thinking, What a fool. You should let her teacher Ji: Gege, do you know who the four great talents are? Swallow: The four great talents are teachers: Of course, who are people? Swallow: Yes ... May reminds me in a low voice: Swallow: Sugar-Coated Berry in Tang Bohu, Tang Bohu. Xiao Lan, don't ask the four gifted scholars. Find out who they are in ten days, and Bai Yan in your tofu: Ah, Emperor Ama, ten days. Emperor: Ten days without bargaining. Teacher Ji: Ok, let's talk about the four great talents and Du Fu and Li Bai for a while. I wonder how much Gege knows about the Four Books and Five Classics. Swallow: Ah, forty-five Jin. That depends on what it is. Everything is different. Must be calculated. Teacher Ji: Do the math. How did Gege work out every difference? This is natural. What is the difference? Swallow: Forty-five pounds. That depends on what you buy. Forty-five pounds of rice like this is one hundred and fifty pence. Soybean, forty-five pounds is another price. Forty-five Jin of firewood is the cheapest millet. I don't really remember forty-five pounds of barley. It's funny. Emperor: Ahem. Xiao Lan's knowledge of Chinese studies ends here. Change the subject quickly or my eyes will fall out. Teacher Ji: OK, OK, OK. Now let's play a word game. Let's be vague. It is easy to write a poem. Please ask the swallow: Ah, my fifth brother: I will teach you how to make the sky foggy and the dew on the grass clear. Fog easily turns into dew. The dew turned into fog. It's hard to get Channel 2: Then I'll teach you how to grind ink on the inkstone. It's easy to turn ink into words. It's easy to turn words into ink. Swallow: I really want to do it. Can we not laugh enough? Teacher Ji: Try it. This topic is really easy. Swallow: OK, I'll write four sentences, too. It's easy for master to test me. It is difficult for me to answer the master's question. Teacher Ji: It's hard to laugh when it comes to the point. Diji: Alas, Xiaolan, Xiaolan, I think you are in the biggest trouble. Teacher Ji: Is it a big trouble?
