This school, named "Public School", is actually a private secondary school. The original intention of Henry VI to name it "Public School" was to provide free education for poor students, so that poor children could also enter the school as a preparatory school for entering King's College of Cambridge University. But because it was run too well, Eton College gradually became the most famous aristocratic school in the UK, which was completely contrary to the purpose of King Henry VI's school. You can often see study tours organized by domestic private schools at Eton College, but they can only look outside like independent tourists. Eton College is a training place for the British royal family, political and economic elites. It has produced 20 British prime ministers such as former British Prime Minister Cameron, as well as poet Shelley and economist Keynes. It is also the alma mater of Prince Charles, Prince William and Prince Harry, the heirs to the British throne.
