In the shade of trees by the river, Professor Shu sat in a lounge chair, savoring the unique aroma of tea as he leisurely sipped it, feeling as if he had already entered the blissful life of retirement, carried by the breeze.
What kind of tea was this, exactly?
Engrossed in studying his cup of tea, Professor Shu held it deliberately.
"Teacher, we've got the soil samples!" A few students came running, ignoring the sweat dripping from their foreheads. "We collected samples from five locations, each consisting of one sample from the surface and another from two meters deep, making ten samples in total. We haven't been able to obtain samples from any deeper locations for now..."
Professor Shu set down his tea cup and glanced at the soil samples: "What conclusions have you drawn?"
The students exchanged looks, and one girl boldly began, "The soil layer here is quite thick, and the geological conditions are favorable for construction..."
