Yes, Mandate of Heaven is not a fairy tale on which you trace your Chinese identity, your skyrocketing high IQ made me feel inferior.
Did I tell you Bharatavarsha means a land between the mountains of North(Himalayas) and seas of the South(Indian ocean, Arabian sea and Bay of Bengal) where our Indian civilization flourished and traced us as people of Bharatavarsha and we have used it since ancient times to modern times, we have a cultural basis of our identity and don't need some Pervert Emperor like Qin Shi Huang to claim it. Bharat was our historical homeland/country, our people never heard of the term subcontinent, geographic expression only high IQ Chinese knew it.
The Qin or Han Empire looks some 20% of modern China, united China. LOL
No united China existed before 1950, even ROC never had a united China.
