I occasionally know that the Nobel laureate Yang Zhenning lived and grew up here. Yang Zhenning's old residence was five years in advance, covering a large area, and it was a large family, so there was no economic worry about studying abroad. Its old house has a side door, the side door is the center of the famous one-person alley in Sanhe Ancient Town. I don't know if the formation of one-person alley is related to Yang Zhenning's fathers. I hope it has nothing to do with it. After all, the formation of one-person alley must be the result of the incompatibility of the two neighbors' building of the courtyard wall. The benevolent see the benevolent see the wise, after all, Professor Yang Zhenning won the Nobel Prize as a Chinese, whether you like or not Yang Zhenning, he still made a face for the Chinese.
