“IRON” the Northeastern Draft Horse (with background story!)

Northeastern Draft Horse(Chinese writing:东北挽马) is a horse breed mainly found in Northeaste China. They are capable of tasks such as horse-drawn sleds.
The Story of Iron:
Golden rice covers the black soil. This is Drift Valley（烟逝谷）, a fictional city in Northeast China, and Iron’s hometown. Once a heavy industrial base, the city transitioned into a tourist destination and grain producer after mineral resources were depleted. Every harvest season, endless fields of plump rice ears sway gently in the wind. Iron pulls a cart past the fields, carrying an internet celebrity live-streaming online. In the industrial age, this draft horse has become a spectacle. Pulling the cart is no longer about reaching a destination, but about the journey itself.
Iron’s literal meaning is "vintage iron", yet in Northeast Chinese dialect, it refers to a loyal best friend. Iron was not always named so. Its owner, deeply attached to the horse, affectionately nicknamed it "Iron". Gradually, the horse forgot its original name.
Its owner says Iron is camera-savvy, yet the horse cannot recognize its own reflection. The owner explains that display devices are ultimately designed for humans, and horses struggle to adapt to them.

Later, Iron made the way to a coastal Equestrian Club called “Equus Future” where the weather is scorching hot all year round, specializing in pulling electric carriages. As the name suggests, the real power of an electric carriage comes from an engine—while the horse is just for providing emotional value.........

**"Northeastern Draft Horse" is not the official English name for this breed. If you want to learn more about it, please search for its Chinese name "东北挽马", as you might find very limited information using this English translation.

金黄的稻子覆盖了黑土地。这里是位于中国东北的虚构城市“烟逝谷”，老铁的家乡。这座城市原先是一个重工业基地，后来矿产资源枯竭，烟逝谷便转型成了旅游胜地，以及粮食产地。每到收获的季节，成片的饱满稻穗总是在风中摇晃，一眼无边。老铁拉着套车从田边经过，车上载着正在直播的网红。在工业化时代，这匹挽马已经成了一种“景观”，拉车不是为了到达终点，旅程本身即是目的。
老铁的名字，字面意思是“vintage iron”，但在中国东北的方言里指“bestie”。老铁原来不叫老铁，只因其主人对其感情深厚，将其昵称为“老铁”，所以老铁也就慢慢遗忘了本来的名字。
它的主人说它是一匹有镜头感的马，但老铁却不认识自己的影像。它的主人还说，这是因为播放设备终归是为人类设计的，马类不太适应。
后来，老铁来到了一座长着椰子树的海边马场，专门拉电动马车。电动马车，顾名思义，真正的动力是发动机，而马只负责提供情绪价值了。
