Gurgaon is a working hub located just across the Delhi/ Haryana state border. It's not technically a suburb since it provides more office than domestic buildings; however it is in striking distance of Delhi, so people can live/ work in either place comfortably.
Gurgaon gives the impression of a new place that is still a work in progress. Each modern building is flanked with building sites.

Sohna is a corrupted form of Sona which means gold. The town is said to have derived its name from the gold dust which was found after heavy rains in the beds of the neighboring torrents. The town is especially remarkable for its hot springs. In ancient times, it was a place of rishis and the main kund (tank) was called Shiv Kund. Famed for medicinal properties, these Sulphur springs were visited by foreign tourists during the British period. Now the government has developed this place into a tourist and pilgrim center.
