In Tongcheng, Anhui, there is a narrow lane six chi wide. Tradition says that in the Kangxi era, the family of the grand secretary Zhang Ying quarreled with their neighbors, the Wu family, over a boundary wall. The family wrote to him.
He answered with a poem: “A letter sent a thousand li, only about a wall. Let them have three feet, what harm is that? The Great Wall still stands today, but no one sees the First Emperor of Qin.” Some versions begin “A letter came, only about a wall.” The Zhang family moved back three chi. The Wu family did the same.
On October 17, 2024, Xi Jinping visited the lane. He said that it shows “the historical wisdom of our ancestors in resolving conflicts.”
