Reply to 2# fossil-zhang Thanks
One year equals 2Y tons, right? It seems that domestic production capacity isn’t that large, is it? Why is it still counted on a daily basis?
The ‘d’ here should not mean ‘sky’, but rather ‘year’. 500,000 tons per day is impossible, but it’s feasible on an annual basis. Surely, I didn’t pay attention to making corrections while writing.
The year is usually represented by ‘a’, not ‘d’; it’s also possible to mistake ‘a’ for ‘d’. In short, if the first 500,000 tons are correct, then something is wrong with the subsequent figures; if the subsequent figures are correct, then there’s an error in the earlier figures. Still, it depends on the context of the sentence; if it’s referring to the daily production across the whole country or the world, well, haha.
