Chương 312: Chapter 312: Just a Sample

Yang Chuxia looked at the somewhat rough model in her hand and said, "Uncle, the wheels underneath can't be made of iron like a wheelchair, but they also can't be made of wood."

"Why?" Yang Dayong didn't quite understand and asked.

Uncle Niu saw the point and said, "The young lady just mentioned that this box is for scholars to use as a book box, so it can't be too large or too heavy, otherwise, it would increase the burden for them. But if you make iron wheels, they will be heavier than wooden wheels. On the other hand, wooden wheels are more prone to damage."

"That's right, Uncle Niu is correct, that's what I was thinking," Yang Chuxia pondered and said, "So, I was thinking, what if we wrap a layer of iron around the wooden wheels, and this time don't put any dents in it."

When Yang Dayong heard this, he also thought it would be much lighter than using iron wheels.

"It should be possible," Yang Dayong nodded, "I'll think about it more later."
