There is a chef who is proficient in poetry. Every time he cooks a dish, he can write a beautiful verse. A scholar deliberately posed a problem and gave the chef two eggs and asked him to cook several dishes, and each dish should represent an ancient poem. The chef happily accepted and cooked four dishes. The first dish is two pure egg yolks and a few shredded green vegetables; the second dish is to cut the cooked egg whites into small pieces and arrange them in a "1" shape, with a green vegetable leaf underneath; the third dish is stir-fried A pinch of egg white; the fourth dish is a bowl of clear soup with four eggshells floating on it. The scholar saw it and expressed deep admiration. The first line: two orioles singing in the green willows. The second line: a line of egrets ascending to the blue sky. The third line: the window contains the snow of Qianqiu on the Xiling Mountain. The fourth line: the door docks the Dongwu Wanli Ship. This Tang poem has been praised by literati of all dynasties since its birth. It was highly praised and gradually became one of the teaching materials for educating students in Tang poetry in various dynasties.
