How was it decided what aspects of Western language Mandarin would inherit and why?
Ex: Western punctuation (! . ?), left to right writing style (in the mainland at least), pinyin vs bopomofo, etc.
Why did they decide to overhaul the language to read left to right top to bottom instead of top to bottom right to left, but choose not to inherit something like spaces? It's not as if a native Mandarin speaker has any trouble reading top to bottom right to left. Was that change made to make it easier for foreigners? If so, why not add spaces as well? If not, why change it at all?
Just wondering the historical context for how these decisions were made.
