Vishnu has adopted 10 villages to support them in whatever way possible.
"He has adopted 10 villages near Sree Vidyanikethan Educational Institutions, Tirupati, to provide the opportunity for the under-privileged community to access good education, good sanitation, clean water and access to primary health," he added.
"The idea behind his adoption is to create holistic and sustainable solutions to the challenges faced by village folks, helping children and families become economically empowered," said Vishnu.
Vishnu is currently busy shooting for two Telugu films - "Doosukeltha" and an untitled Telugu multi-starrer with brother and father.
