Classic Detective is a term used to describe a type of detective character that has been popular in literature and film since the early 20th century. The most famous example of this type of detective is Charlie Chan, a fictional Chinese-American detective created by Earl Derr Biggers. Chan is known for his intelligence, wit, and ability to solve complex cases. He is also known for his catchphrase 'Confucius say' which he often uses to explain his deductions.
