so much for high IQ.
CHINA , as in PRC controlled by CPC and PLA today, is NOT a Nation or Civilisation or Empire. (You could make a case for an empire but Kingdoms have to have reasonably autonomous Armed forces and institutions.) PRC has Tibeto-Burman, Chinese, Turko-Mongolian(Islamic) cultures, and doesn't qualify as a single civilisational entity. Forget about your claims of being a single Political entity from 220 BC. Today, PRC is a Political entity surviving on the recongnition by the powers that form the World order of 20 th century post WWII. IF you remeber, CPC keeps begging countires to recongnise Taiwan and until recently Tibet as Chinese territories. Hence, You, like many chinese I interacted with, try to "Prove" PRC-China (Empire and later Nation) since 220 BC BS. It comes from deep sense of insecurity and being subconciously aware of the fact that China-PRC is really 4 Nations including your own Middle Kingdom which occupies the other nations. This also makes you to see the ghosts of British invented India once in a while in forums like this, ignoring everything about India as described by Ancient Greeks, Chinese, Arabs(travellers and Kings) and later in the middle ages.
INDIA, as in Republic of India, is Not only a civilisation with roots in IVC expanding into whole of subcontinent, but also a 'civilised' Union of recongnised states like EU or US as defined in it's constitution since 1950. Indians as one Nation can be only understood within Indian cultural Paradigm, for which I am afrad one has to be able to understand Sanskrit. The British did, hence called it British India, as opposed to building it from the scratch in the 19th and 20th centuries.
We didn't have cultural revolutions or giant leaps forward for "Nation building" like in China. Indians didn't need those and did not even have Political Revolutions like in Russia(often in the Middle Kingdom before the the founding of PRC and chairman MAO).
