Karthi has always found time to promote social causes and is involved in social welfare activities, encouraging fans to do likewise through the "Makkal Nala Mandram", a social welfare club.
He became a brand ambassador to promote awareness and also did a short film on how to fight dengue fever. Recently he was seen dancing with orphan children for ‘corporate chill out 2013’.
It is the annual fund rising show organised by Aruwe, the social welfare organisation that takes care of destitutes and orphaned children.
Karthi who is busy with the shoot of his Venkat Prabhu directed Biriyani found time to interact with these children. It is a great gesture by the actor.
