The origin of Idioms
In the Analects of Confucius, Zi Zhang said: "the wall of Confucius is several Ren, and you can't enter through the door. You can't see the beauty of the ancestral temple and the wealth of officials." Han Ying's "Han Shi waizhuan" Volume 7: "Fu Chun's peach and plum trees have shade in summer and food in autumn; spring's Tribulus terrestris can't be picked in summer but thorn in autumn."
Idioms and allusions
During the spring and Autumn period, Uncle Wu, a senior official in the state of Lu, praised Confucius' student Duanmu CI (Zi Gong) as better than Confucius. Zi Gong said that he could only walk into Confucius' gate wall. Yang Hu committed a crime in Wei state. He fled to Jin State in the north and told Zhao Jianzi that half of the officials in the imperial court were his students. Instead of helping him, they harmed him. Zhao Jianzi said that what he cultivated was not peaches and plums, but Tribulus terrestris
