"It was freezing last night. I could hear the wind constantly blowing against the window frame."
"That's right. Still, my family and I feel warmer than before since moving into our new house. Our new place has no air leakage, so it helps us stay warm."
"That kid who helped build our new house is talented. Our house can withstand an earthquake and keep us warm during winter."
"Yeah, I didn't need charcoal last night, either. My brick bed didn't get cold at all."
"Although the charcoal here is cheap, we usually can't bear to use it. People from other villages come here to buy charcoal, too."
"Su Fengzhi and his two sons must be busy making a lot of charcoal to keep up with the demands."
"It is winter, after all, so more people need charcoal. Su Wenlin and Su Wenchi are capable enough to keep making more charcoal, but they still hire people to help them."
