A copywriter of a film company, while preparing for a recent TV series, became deeply involved in that mysterious history. He hoped to go back in time, be a witness to history, and then come back to provide first-hand information. Filming a historical drama, or becoming famous as "The Forum" is also a good choice. As God wished, she really wore it. She not only became a witness to history, but also became a participant. She wanted to stay out of it, but she couldn't hide.
