China is one of the countries with the longest histories in the world.-the correct answer is: china is one of the countries with the longest histories in the world.chinese are very proud of their historical heritage. documented chinese history stretches back some 5,000 years to the xia dynasty. yet what is now considered china was first unified around 221 b.c. under emperor qin who ushered in the imperial era when a number of dynasties ruled over the country. imperial china suffered a sharp decline in the late 19th century and became subject to many western powers who according to the constitution, gradually reduced [china] to a semi-colonial and semi-feudal country. the preamble goes on to praise the revolution of 1911, led by dr. sun yat-sen, that abolished the feudal monarchy, and ironically was the origin of the republican movement that waged civil war against the communist party of china. the communists eventually overthrew the opposing rule of bureaucrat capitalism in the revolution of 1949, under the leadership of mao zedong, whereupon the chinese people took state power into their own hands and became masters of the country.
