The train K323 departs from Tianzhou City, passes through Haizhou City, and heads west into neighboring provinces, reaching Heishui City and Poplar City.
Yang Baohua has worked on this train for thirty years.
Since this train was a green passenger train labeled as 323, Yang Baohua has been working here.
In the blink of an eye, thirty years have passed, and in three to five years, Yang Baohua will reach retirement age.
In the train chief's resting room, Yang Baohua is imparting experience to his newly recruited apprentice.
"As train police, we need to be meticulous, and also bold."
Yang Baohua takes out his phone, showing an old photo: "This was twelve years ago, during a theft case on our train."
"Look at this suspect, wearing glasses, looking quite refined, seemingly nothing suspicious."
"But look at the calluses on his right thumb and index finger. Back then, thieves used blades to cut pockets."
"They practiced using the thumb and index fingers to hold the blade."
