While I am in no position to speak on behalf of the authorities in Beijing, the government of the People's Republic of China, unlike those of many Western countries,
generally speaking refrain from interfering with or intervening in the domestic affairs of foreign nations.
Not to say they don't sympathize with your supposed plight or alleged troubles, but unless you and your family are Chinese citizens, the Chinese authorities are absolutely
not going to help you or raise your issue with the Indian authorities.
It's simply not their problem to resolve. May I suggest that you contact a NGO like
or
? They may be more interested in hearing you out than the Chinese authorities or any of us here. God bless!
