What is the experience of watching a TV series but not acting it?

When I was a child, I loved Angie Chiu's The Legend of the New White Snake. I was particularly fascinated by the episode in which she was locked up in Leifeng Tower. At that time, there were two groups of people pulling Xu Xian while pulling the White Snake. Xu Xian cried sadly, "Madam!" The White Snake also cried sadly: "Officer!" I was very sad when I watched it, and I got into the play. He told my brother all day: "Officer, it's so dark and cold in Leifeng Tower. I was scared. Officer, please help me. " At that time, I was once looked down upon by my brother. This kind of immersive feeling is probably that I thought I was in the theater, but I was actually just a theater goer. Even if you play again, you are just reading other people's stories.
