Everybody learns from everybody, some more than others. Much of the mathematical, scientific and cultural "discoveries" that are wrongly attributed to Europeans/Americans were in fact Chinese origin (many going through Persia, Arabs first before arriving in Europe).
Did you know there's no such supporting evidence for 'Pythagoreas' theorem, but hundreds of years PRIOR it was invented/discovered in China?!!!! Also the violin and guitar (one being the main instrument of classical music, the other modern) is a CHINESE INVENTION?!!!!
These are just a few of the examples. Contrast that with India's contributions.....
So please get off your high-donkey. The envy India feels is that they can't even produce, invent or create the most basic stuff they mock China of.
