1, why Jinan is called Quancheng:
This is the beautiful city, which is famous for its rich springs and beautiful scenery. Jinan once had hundreds of springs, including Baotu Spring, Black Tiger Spring, Wulongtan Spring and Pearl Spring, and 733 natural springs, enjoying the reputation of "seventy-two springs". Rare cities at home and abroad, it is a unique natural karst spring museum. In addition to "Spring City", Jinan is often called "Spring Capital". The springs in Jinan are not only numerous, but also varied in shape and colorful, some spewing out, some waterfall-shaped, and some lake-bay-shaped. Many cool and sweet springs gush from the underground of the city and flow into rivers and lakes. In the peak season, in areas with dense spring, the beautiful scenery of "every spring brings tears to everyone" and "crystal stone in the stream" is presented. As early as the Song Dynasty, Ceng Gong, a writer, commented: "Qiduo Ganquan is the best in the world", and Yu Qin, a geographer in the Yuan Dynasty, also praised: "Jinan's mountains and rivers are the first, and springs are the first in the world." The clear and sweet spring water is the blood of Jinan, which endows the city with exquisite temperament and vigorous vitality. At the same time, Jinan's urban development, historical evolution and folk customs are also closely related to spring water, forming a unique spring water culture.
2. Why is Kunming called the Spring City?
Kunming has four seasons like spring. It is not cold in winter and not hot in summer, so it is called "Spring City".

In winter, the solar altitude angle is larger than many other areas in China, with relatively long sunshine time and higher temperature. ② Located in Yunnan-Guizhou Plateau, with high altitude, strong solar radiation, long sunshine time and high temperature; (3) Close to the Indian Ocean, regulated by the ocean, the temperature is not low. The reasons why it is not hot in summer are: ① it is located in the plateau, with high altitude and low temperature; (2) The temperature is not high due to ocean regulation. This is called "Spring City".
3, the degree is called Jincheng reason:
It is generally believed that Shu Han set up brocade officials in Chengdu during the Three Kingdoms period to concentrate brocade craftsmen and manage brocade. During the Western Han Dynasty, the silk industry in Chengdu was unprecedentedly developed, and Chengdu was the main producing area and trade distribution center of silk handicrafts. During the Shu and Han dynasties, Chengdu's brocade handicraft industry was particularly developed, and "Shu Brocade" was famous all over the country. It is the main commodity of Shu-Han foreign trade and the main source of financial income of Shu-Han regime. Therefore, the Shu Han Dynasty set up a special "Jinguan City" to concentrate brocade craftsmen, manage the production of Shu brocade, and build a special city to protect the production of Shu brocade, which is called "Jinguan City" and later referred to as "Jincheng City".
