"When it's time to build the walls, that's when we'll need the cement," Zhang Dazhuang said after he'd had his laugh.
"Uh..."
Gu Nuan Nuan broke into a nervous sweat. She really didn't understand anything about building a house. 'Grandpa's "cement house" is probably a little different from the reinforced concrete buildings of the future, right?' After thinking for a while, she still couldn't let it go and asked again, "When there wasn't any cement, what did people use to lay bricks?"
"Well, people weren't so particular back then. Some didn't even use bricks, just adobe. Or they'd mix straw and mud together to build the walls. But while those methods cost a lot less, they're nowhere near as sturdy as using cement," Zhang Dazhuang said with a smile. "A house is built to last a lifetime, or even several generations. Naturally, the sturdier, the better."
"Ohh..."
