After getting off the train and looking at the chaotic train station in City X, Fei Fei didn't know why she came to this city. She just walked forward step by step with a simple and thin luggage bag in her hand, thinking about the phone call from her mother on the train.
"Fei Fei, where are you going?"
...
"Mom, I just want to stay outside for a few years. It'll be fine."
"Hey, Mom, I won't say much to you anymore. My daughter is getting older and she always has to fly away. Remember to protect yourself. You have to go home during the New Year and the holidays, so call home often. Do you understand?"
"Well"
"The weather is getting cold now. Remember to wear more clothes. You silly girl doesn't know to bring more clothes when you go out. All the thicker clothes are at home. When you apply for a bank card someday, tell your mother that she will give you money to buy some clothes."
"... Well"
"Call me when you get there. Use a landline. It's cheap."
"Well... Mom..."
There was silence on the other end of the phone. Fei Fei slowly said three words "I'm hanging up" and then closed the phone and turned off the power.
