China was unified in 220 BC. We were civilized by ourselves 4000 years ago when you were still barbarians. Confucius and Taosim has been around since 2500 years. Buddhism reached China in 600 AD.
CHina was the center of the ancient world, all missionaries and traders had to pay tribute to the emperor, that why buddhist came to china, parco polo came, muslims came, persians came. Boddidharm was lucky the emperor gave his permission to stay, otherwise he had to pack his bag home. Such is the greatness of Chinese empire.
India was primitive, the ones who go to India was to conquer you, LOL. Central asian muslims ruled you for 800 years. Thanks to the British, india was created in 1947.
Now go back to your mental hospital.
