In the twenty-third year of the Republic of China (1934), Longyin Town was a closed ancient town in the Yangtze River Basin. Steam locomotives and rickshaws run side by side in the bluestone alleys, and British-made street lamps glow pale in the rainy night. The town retains the Bagua-shaped drainage culvert built in the Ming Dynasty. Every time there is a heavy rain, it makes a whimpering sound, which is called "Ghost Dragon Yin" by the locals.
