Ya there are many temples in Tamilnadu which I have seen in Vijay tv. The temples solved their problems like disease, marriage, no child. But I dont know the name of the temples. I didn't remember anything.
On my experience I visited a temple in Andhra Pradesh. Name of the temple is Visa Balaji temple located at Hyderabad. My family members said that "What you ask to the god it will happens". If the thing you worshiped to that temples comes true then you have to again visit that temple and do "108 rounds".
