How does Daniel know that Jesus was teaching at Capernaum?

In Chapter Five, Daniel arrives in Capernaum, and he is like a tourist taking in all the sights of the markets with food and cloth vendors. He also goes to the harbor where he is given a cooked fish by a friendly lady. She asks him if he is waiting for the teacher. Not knowing what she is talking about, he says that he is not. She urges him to follow her to hear the "carpenter" speak. The carpenter is Jesus.
