One of the main reason behind the 'developing' state of India even after 70 years of independence is its differences which Indians still have in their mind. The language barrier is the only barrier which is proving to be resistance let alone culture prevention and all that. Languages are just a form of communication between people and people should accept it. People should learn languages like English(Which have vast…
"chinese" isn't one language. It's a set of many languages which share some grammar and a common logographic script (though the script isn't used in exactly the same way for each, e.g. Beijing will write/say 哪儿 instead of 哪里 for "where?" -- there are many other differences but I don't know enough to give a clear idea of its scale).
The spoken languages are quite different otherwise, at least as different as European romance languages. There is a "Standard Mandarin (普通话)" however; which the government has pushed and is spoken by most residents of Mainland China.
I'm skeptical that this is a good way preserving the culture. If language does have an effect of preserving the culture; this move would also have effect of killing subcultures from regions (which may indeed have happened in China; though I don't know). China and India are both pretty diverse culturally.
You're making the argument that the popularity of English is detrimental to the preservation of Indian Culture and in the same breath suggesting forcing Hindi on everyone as a solution, as if it wouldn't have exactly the same effect on a culturally diverse country.
