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.
The stripes represent the original 13 Colonies and the stars represent the 50 states of the Union. The colors of the flag are symbolic as well; red symbolizes hardiness and valor, white symbolizes purity and innocence, and blue represents vigilance, perseverance and justice. Our flag is an inspiring symbol that unites us all as American citizens. The unique history of the American flag follows the history of our country and reminds us of the triumphant beginning of the United States. The 13 stripes: a symbol of the first 13 colonies. The stars: a symbol of our country's 50 United States. As our country grew and developed, so did our flag. It has followed the fate of the country itself and, in the future, our flag may even change again.
