Why are the two sentences "Old wells, green bamboos reflect green lotuses, green bricks and small tiles generate green smoke" used when describing Chengdu's Shaocheng and Kuanzhai Alleys? What is the origin of these two poems?

This is just a portrayal of the characteristics of Chengdu alleys, but it has its origins. In the 61st year of Kangxi (AD 1722), the imperial court transferred 1,600 Eight Banners soldiers to Sichuan. The governor of Sichuan allocated the original site of Shaocheng in the Qin Dynasty to the Eight Banners soldiers as a camp. These Eight Banners soldiers brought with them the architectural pattern of the north and also brought Hutong in Beijing. With the integration of water and soil for more than 200 years, the hutongs in the old Chengdu Shaocheng City have gradually been branded with Western Sichuan culture, and the hutongs have gradually become the alleys of Chengdu people. The alleys in Chengdu are very simple and elegant in color, with green-gray small green tiles and black beams and railings. The courtyard is the most important building in the alley. The courtyards in Chengdu are different from the rich and powerful in Beijing, and have their own simple and elegant style. The patios in the large and small courtyards of old Chengdu are a major feature. During the demolition process of the narrow alleys, not only a large number of ancient well sites were excavated, but also a large number of Qin bricks, Han tiles, and ancient pottery pots were unearthed. These two sentences seem to describe the scenery, but in fact they imply the profound historical and cultural connotation and unique architectural style of old Chengdu.
