Soham, Most of what you say is right. However regarding Shanghai there is a "hooka" system in China. Its mainly to prevent influx of migrant workers who flock Shanghai in name of earning livelihood. HOWEVER the difference is that it doesnt stop these people on which region they come from. If the people are sponsored by any company/office based in Shanghai there are some formalities which need to be completed and the "hooka" can be obtained. This system of claiming Mumbai is only for certain"tribe" of people is absurd. Development will happen only with open mind and futuristic policy - not by being regionilist or chauvinist...
