"Hamlet" is the pinnacle of Shakespeare's tragedies and one of his four major tragedies. It has reached unprecedented depth and breadth in ideological content, profoundly revealing the sins and essential characteristics of late feudal society. Based on an ancient Danish myth from 1200 AD, it tells the story of a Danish prince who pretended to be crazy in order to avenge his uncle who killed his father, married his mother and usurped the throne. After being tortured, he finally took his revenge. The entire story of "Hamlet" is permeated with the spirit of Shakespeare's era and is the most profound expression of Shakespeare's humanism and critical spirit of real life.
