This is not the slogan raised by any chauvinist programne. A visit to north chennai shows the development index. Traditionally, north chennai houses big industrial plants. Mainly, the plants represent old brick economy. The constant movement of heavy vehicles have made the roads not fit for any transportation.
Just wear a white shirt and visit the industrial belt. Definitely, your shirt will carry all dirt and grime.
The northern part of the city is desperately crying for improvement in infrastructure.
But, the inhabitants have learnt to live with the current situation. What else one can do?
On the contrary, south chennai is perched on a safe zone. The infrastructure is far superior. This part of the city houses all major software companies.
