Who knows the story of Ban Chao joining the army (brief)

Ban Chao, a native of Pingling County, Fufeng County, is the youngest son of Ban Biao, the magistrate of Xuxian County. He is ambitious and informal, but he has a good moral character. He often does hard work at home, and he doesn't take doing low-paid things as a shame. Ban Chao is eloquent and well-read. In the fifth year of Han Yongping, Ban Chao's brother Ban Gu was recruited as a school extremely by the court and went to Luoyang with his brother and mother. Because of his poor family background, he was often employed by the government and made a living by copying books, which took a long time and was very hard. He once stopped his work, threw his pen aside and sighed, "As a gentleman, although he doesn't have any outstanding strategies, he always has to learn from Fu Jiezi and Zhang Qian, which have made great achievements abroad, in order to be promoted. How can he always make a living by doing this kind of pen and ink? " Colleagues around laughed at this. Ban Chao said: "How can ordinary people understand the mind of people with lofty ideals?" Later, he went to see a fortune teller, and the fortune teller said to him, "Dear senior, although you are an ordinary scholar, you will be shut out thousands of miles away in the future." Ban Chao wants to know. The fortune teller pointed to him and said, "Your chin is like a swallow, and your head and neck are like a tiger. Swallows can fly and tigers eat meat. This is the fate of Wan Li. " After a long time, Ming Di once asked Ban Gu, "Where is your brother now?" Ban Gu replied, "I am helping the government copy books to support my mother." So Ming Di appointed Ban Chao as an official of Lantai. Later, he was dismissed because he made a mistake.
