In 11 August's episode, it was shown that Bali was Virochan's ancestor. But, in reality, the case is just the opposite. The fact is that Bali was Virochan's son. The serial showed it just the opposite. Another wrong thing is that virochan was shown as maternal grandfather of Vajrajwala. But he was her paternal grandfather.
Virochan was Bali's father. Hiranyakashipu's son was Prahlad; Prahlad's son was Virochan and Virochan's son was Bali. Ravan was born many years before Ram.
