Dear, Student,
Answer to your question is as follows :
Kalidas is known for his plays depicting life in the king's court.
An interesting feature about those plays was that the king and most brahmins are shown as speaking Sanskrit,
while women and men other than the king and brahmins used Prakrit.
His most famous play, Abhijnana Shakuntalam, is the story of love, between a king named Dushyanta and a woman named Shakuntala.
In the play, an interesting description of the plight of a poor fisherman is found.
