Playing the hero for the first time, Fan Wei was worried that he was "not like" Lao Wang played by Fan Wei in Railway Hero. He was always dressed in black and had a flattering face, which left a deep impression on people. Lao Wang is the dispatcher of the railway station because undercover is misunderstood and despised by many compatriots in Japan. He tried his best to get information and convey it. Every lonely and tenacious look is a silent line. From disguise to emotional outbursts, full inner drama left a deep impression on people, but it was very challenging for Fan Wei to portray this role. Fan Wei said: I'm still very nervous. Facing a role, I'm afraid I can't play it well. I have a lot of mental baggage when I shoot every day, so I have to be extra careful when dealing with the role. The role of Lao Wang is very different. I have played many comedies and many little people before, but this is my first time to play a hero. I like this role very much, and I'm worried, because I'm afraid that people will think this role is not like the hero in people's minds after the performance, but the director said it very well. He said he would play a heroic role. Maybe I don't look like a hero, but I will be confident after grasping the spirit.
