"By the way, when was the well in this courtyard dug?" Lin Yan pointed to the water well and asked aloud.
"You've been away from home for a while, I forgot to tell you."
Lin Lei said, "In the square, carrying water always required going down to Bull Horn Mountain, back and forth, far and heavy. In Linjiang Square, only a few households had access to a water source, so it was possible to dig a well."
"Some time ago, I learned some knowledge about observing celestial patterns and surveying the terrain from Mr. Lu."
"Mr. Lu said, here in Linjiang Square, near the slaughterhouse, there was a severe subsidence underground, and later, the transformation near Dayin River also had a huge impact."
"The elderly man let me use this little knowledge to survey the buildings in Linjiang Square and then report to him, about what major and permanent changes in the terrain had happened after the two disasters."
