Among the 663 administrative cities in mainland China, four direct-controlled municipalities, 293 prefecture-level cities, and 366 county-level cities together form a vast urban system. When tracing the evolution of city names, most people first think of ancient capitals like Beijing, Nanjing, and Xi'an, all of which have undergone multiple name changes throughout history. Beijing was once called Jicheng, Youzhou, and Beiping, while Nanjing was historically known as Jinling and Jiankang—these changes reflect the rise and fall of dynasties.

Among the many cities with rich histories, Chengdu stands out as a legendary chapter in China's urban development history, having maintained its name unchanged for over 3,000 years. From the "Chengdu Prefecture" recorded by Japanese envoys in the Tang Dynasty, to the "Chengdu Circuit" defended by the anti-Jin general Wu Jie in the Song Dynasty, and even the "Chengdu Province" mentioned by Marco Polo, the city's name has remained remarkably stable—a rare phenomenon in the global history of urban nomenclature.

The decisive role of geographical patterns in urban development is particularly evident in Chengdu. The Sichuan Basin, surrounded by the Tibetan Plateau, the Yunnan-Guizhou Plateau, and the Qinling-Daba Mountains, forms a natural geographical unit. The approximately 18,800-square-kilometer alluvial plain of Chengdu not only provides superior agricultural conditions but also creates an ecological advantage where "water and drought are manageable, and famine is unknown." This geographical endowment gave it strategic value as a defensible stronghold in the pre-industrial era and made it a hub for goods distribution.

In contemporary urban competition, Chengdu showcases a unique charm that blends tradition and modernity. In the 2020 GaWC World Cities Ranking, Chengdu rose to the Beta+ tier, becoming the first city in central and western China to enter the global second-tier strong city category. As the pioneering "Park City," its built-up area boasts a green coverage rate of 43.5%, achieving an organic unity of historic district preservation and new urban development.

In terms of urban happiness indices, Chengdu has topped the list of "China's Happiest Cities" for 13 consecutive years. This quality-of-life advantage is rooted in its distinctive urban cultural DNA: it inherits the artistic tradition of "brocade city's daily music" while fostering a modern ethos of inclusivity and innovation. The Chengdu dialect's philosophy of "Bashi De Ban" (perfectly comfortable) reflects a balanced urban rhythm that harmonizes fast and slow paces.

Regarding cultural heritage, landmarks like the Jinsha Site, Wuhou Shrine, and Du Fu Thatched Cottage connect a 4,000-year civilizational thread. With 196 intangible cultural heritage items, traditional arts such as Sichuan opera face-changing and Shu embroidery techniques have been revitalized in the digital age through creative transformation. This cultural continuity provides a solid foundation for urban identity.

Looking back at urban development history, Chengdu's sustained prosperity demonstrates the interplay of geographical endowment, cultural accumulation, and institutional innovation. From the cradle of ancient Shu civilization to a national central city, the constancy of its name reflects the continuous upgrading of its urban functions. In the new era of urban competition, this millennia-old city is writing a new legendary chapter in China's urban development by balancing tradition and innovation—and it warmly awaits visitors from around the world.
