The cause is a dream:
In the early years of the Republic of China, the beloved girl was escorted back to her hometown. I heard the whistle blowing, and on impulse, I jumped on the train that had just started. I called her name from carriage to carriage, and then she came... And finally we parted ways.
After leaving the platform, I found that it was an unknown town in the south of the Yangtze River: a narrow bluestone road with a few clumps of green bamboo and plantains beside the road. It was drizzling.
In the middle of the night, I stood in the small station and looked up at the train timetable on the wall. In a blink of an eye, I noticed that several coolies sitting on the floor by the wall were looking at me in surprise. I was surprised to find that tears were streaming down my face.
So I woke up, and immediately found that my quilt pillow was wet with tears. If anyone has had the same dream, please allow me to say: I have been looking for you for a long time!
