As noted by the other Brainly user's response here, early Chinese civilization developed between the Yangtze River and the Huang He River (or Yellow River), because the plain between the rivers is fertile, allowing for the development of agriculture. It's also worth noting that the these two rivers extend for hundreds of miles from west to east before reaching the sea. This facilitated trade and transportation on the rivers. It also allowed Chinese rulers to maintain control and communication across the wide expanse of main Chinese territory.
Also worth noting would be the mountains and deserts and ocean that set China off from other lands. Large mountain ranges exist in the south and west regions of China -- such as the Himalayan Mountains, Kunlun Mountains, and Tianshan Mountains. The Gobi Desert sits in the northern part of China, and the Pacific Ocean is to the east. These various geographic features set China off from other lands, so that civilization there developed in its own unique ways, apart from outside influence.

Between 1880 and 1900, cities in the United States grew at a dramatic rate. Owing most of their population growth to the expansion of industry, U.S. cities grew by about 15 million people in the two decades before 1900. Many of those who helped account for the population growth of cities were immigrants arriving from around the world. A steady stream of people from rural America also migrated to the cities during this period. Between 1880 and 1890, almost 40 percent of the townships in the United States lost population because of migration.
