Jiang's wife especially likes traveling in the mountains. Once she came back from France, she told Jiang that she liked French buttonwood. So Jiang introduced 20,000 buttonwood trees from France and planted them in various streets, hoping that his wife could see her beloved buttonwood trees everywhere in Nanjing.
Before that, it was said that a French missionary loved buttonwood, but he was also very devout to Sun Feng 'an. So at the ceremony of welcoming Sun Feng 'an in China, he took his favorite buttonwood as a gift and specially applied for the mayor of Nanjing to plant it in Nanjing, so that Zhongshan Road was shaded.
