Iron Horse | Iron Horse Made of Iron Barrel

Description:

First of all, it must be made clear that "iron horses" usually refer to traffic isolation facilities or guardrails, and here they are modified from iron barrels, so the core should revolve around the characteristics of "iron barrel modification", combining practical scenarios, production processes, functional characteristics, and cultural connotations. Just like when I wrote about hairtail rice before, it has both practical details and the logic and meaning behind it.
