The key difference is in the depth and detail people are looking for. For those who want a quick overview of a historical period, watching a few documentaries is a good choice. But for a deeper understanding, reading a book is necessary. People usually watch TV for just an hour or two, so documentaries have to cover a lot quickly and might miss things. Books, on the other hand, can provide more comprehensive coverage without this limitation.
關鍵差異在於人們所尋找的深度和細節。對於那些想要快速瀏覽一個歷史時期的人來說,觀看一些紀錄片是一個不錯的選擇。但要更深入地了解,閱讀一本書是必要的。人們通常只會看電視一兩個小時,所以紀錄片必須迅速涵蓋很多內容,可能會錯過一些東西。而另一方面,書籍則可以提供更全面的覆蓋,而不受這種限制。
