Going to the sea is a symbol of a country and a nation's modernization. Break through the winding coastline of Europe from Diaz and arrive? From Gamma to the opening of a real new air route, and then to Columbus' discovery of America, which will become the world economic center in the future, Magellan exchanged his life for geopolitical rebirth, and the world moved from a closed and isolated ancient history to an open and interconnected modern history. From then on, Europe gradually took off the long and dirty teaching clothes of medieval priests and conquered the world with gunpowder and compass from eastern countries. As inscribed on the reef of Dias Navigation Monument: "This is the end of land, but it is the place where dreams begin."

In China, due to the restriction of natural economy and agricultural civilization Confucianism, the ancient understanding of the ocean was only a mysterious and desolate place. In modern times, with the western powers coming from this mysterious and desolate place and opening the locked door of this ancient country with artillery fire, the Chinese nation began to re-examine the endless blue with a rational eye, and the most primitive desire for life gradually emerged.

Due to the special historical conditions in modern times and the Anshi Rebellion, the economy in the south of the Yangtze River has always been at the core of the economy, and the economic center of modern and even modern China naturally fell on the southeast coast. This situation continues to this day. This has also caused a general awareness in the hearts of Chinese people-the east and the coast are good places to get rich.

As for whether a city is centered on the east and spreads around, it depends on the regional pattern of the city itself. For most coastal cities and coastal plain cities, the vast area makes them form a "centralized" regional form that develops at will regardless of the terrain. This regional form is characterized by the plane distribution of the whole city, flat and wide streets, and the administrative center often develops in the center of the city, residential areas and industrial areas to the periphery. Beijing, for example, is a good example. In such cities, industrial development often forms a "cluster effect", that is, a large factory is the center, and its supporting equipment factories or garbage disposal plants are distributed around it. For example, taking the old Shougang as an example, Shougang Group is located in the east, so around Shougang's blast furnace, coking plants, rolling mills, sewage treatment plants and other supporting factories are densely distributed, forming a dense and complete industrial zone, and residential areas, that is, workers' residential areas, must be located in or around this industrial zone, forming a huge industrial network. There are many factories, sufficient workers, advanced technology, policy support and high popularity here, which will inevitably attract many other factories or businesses to set up factories. In this way, the industrial center and economic center of the whole city will move eastward, which will form what you said, "Many areas in the east of the city are bustling places, and the look and feel of the city is better." One question is, how did the first domino in this chain reaction choose "East of the City"? Or, why does the starting point of urban industrial economy lie in the east rather than the west? It needs to be studied in combination with the geographical location of China. China, located in the east of Asia and the west coast of the Pacific Ocean, is the largest monsoon region in the world. If a city is located in the coastal coastline, the flat and open terrain in the east, the port with convenient transportation and the climate with warm winter and cool summer, it is obviously the best choice for economic development relative to the west. Even in inland areas, the "complexity" that has always been close to economically developed areas and the "water tendency" that has always been close to the coast will inevitably affect the signature pen of decision makers; In addition, it must be said that the monsoon climate in China makes the wind direction northwest-southeast all the year round, that is, southeast wind in summer and northwest wind in winter. In this way, in order to prevent the waste gas and waste residue discharged by factories from drifting with the monsoon, the economic centers of most cities in China are located in the eastern suburb perpendicular to the prevailing wind, which is also an important reason why the eastern part has become an economic center.

The above situation applies to a large number of cities in China, and may also give you the impression that "many cities in the east are prosperous places and the city has a beautiful look and feel". It should be noted that some cities that are greatly influenced by topography, such as Chongqing, where Jialing River flows into the Yangtze River estuary, Lanzhou and Yan 'an in the Yellow River basin, do not "not go eastward", but develop according to local conditions in combination with their own topographic characteristics.
