白居易是我国历史上名诗人，但人们还不知道他是个“绿化迷”。他无论到哪里做官，总要种花、栽树，所以，在他所走过的地方，都流传着与绿化有关的故事。 公元 819年，白居易被贬谪忠州 (在四川 )刺史时，见城周山岗满目荒芜，感慨之余，挥毫写下了“巴俗不爱花，竞春人不来” Bai Juyi is a famous poet in Chinese history, but people do not yet know he is a “green fan.” No matter where he is an officer, he always planted flowers and planted trees. Therefore, wherever he went, stories about greening were circulating. In 819 AD, Bai Juyi was relegated to Chungju (Sichuan Province) when he saw the barbarians in the city and mountains. When feeling uncomfortable, he wrote down the message that “the bar does not love flowers, and the spring does not come”
