47-year-old Li Wenrong is the "old face" on No 5630 train. In 2009, by chance, Li took the train out of the village for the first time at the direction of her family. Because the train ticket was cheap and the timetable was reasonable, Li came up with the idea of taking the train to sell vegetables. She said that the first time she shipped vegetables to sell, she was pleased with the results. "I sold out in less than 10 minutes, and the income was good!"

Feng Xia, a Songshan villager, has sincere appreciation for this train. She helps villagers check the train's running times and also teaches them how to use WeChat to track the train. She used to follow her mother on this slow train to sell vegetables. Now, she carries the vegetable basket herself and sells them from the train. "It's all seasonal vegetables and fruits, and sometimes it comes with homemade peppers and dried beans to sell."
