The "Cold War" had that name because the two superpowers (the USA and USSR) did not fight a direct "hot" war against one another. They engaged in a protracted stand-off against each other, and had an arms race of nuclear weapons and military strength. They also supported "proxy wars" where they took opposing sides in conflicts happening in other parts of the world (such as the Six Day War in the Middle East).
Further detail:
Some of the deeper issues that caused rivalry and tension between the United States of America (USA) and the Union of Soviet Socialist Republics (USSR) were that the USA was committed to capitalism and democratic institutions of government, whereas the USSR was committed to communism and imposed authoritarian government. The Cold War was mostly a tension between these worldviews.
There were also immediate conflicts and pressure points as the Cold War began in the late 1940s (after World War II). One of those issues was that the USA had atomic weapons and the USSR did not. (The US would not share that technology with the Soviets, who had been their ally in World War II.) When the Soviets developed their own atomic weaponry, this led to a massive arms race between the superpowers -- which brought significantly more tension to the situation. Further tensions developed over which nations would be aligned with each of the superpowers -- either with the USSR and communism and with the USA and its democratic, capitalistic worldview. And (as mentioned above), the two superpowers aided differing sides in conflicts that took place in various parts of the globe during the Cold War years.

Answer:
Most people in Tang times were farmers. Out in the countryside, homes were made of bamboo and sun dried brick. They were simple, one room homes. The people wore simple clothes.
During the Song (Sung) Dynasty (960-1276), technology was highly advanced in fields as diverse as agriculture, iron-working, and printing. Indeed, scholars today talk of a Song economic revolution. The population grew rapidly during this time, and more and more people lived in cities.
The Mongolian pastoral nomads relied on their animals for survival and moved their habitat several times a year in search of water and grass for their herds. Their lifestyle was precarious, as their constant migrations prevented them from transporting reserves of food or other necessities.
During Ming times (1368-1644) about 90 percent of the Chinese still lived in villages, most of which had about fifty families. Villages were usually smaller in the north than in the south. Few Chinese lived in single families on isolated farms. Villages were real communities, small gathering places for group activity.
