Ban Gu's attitude towards the knight-errant was appreciated in the Biography of the Ranger in the Book of Han. He believed that rangers were a group of people with special talents and courage in ancient society. They were not only good at martial arts, but also had a sense of justice and chivalry. Ban Gu praised the knight-errant in the biography of knight-errant:"The knight-errant's deeds are imitated by the world, even if there are thousands of people, I will go." It meant that the actions of the rangers were imitated by the world. Even if I faced thousands of people, I would still bravely advance. In addition, Ban Gu also described the heroic deeds of the rangers, such as helping the righteous, protecting the weak, and fighting evil. They showed their fearlessness and righteous spirit. Therefore, it could be said that Ban Gu wrote the biography of the ranger very seriously and highly praised the image of the ranger.
