How it's used
Refers specifically to the period of childhood and is almost exclusively used in spoken contexts. It functions as a time adverbial placed at the beginning of a sentence or immediately after the subject. It carries a nostalgic tone and is frequently used when sharing personal anecdotes or comparing past habits with the present.
Examples
I loved going to the park to play when I was young.

Common mistake
Avoid using it to describe the youth of others in a formal or objective sense, as it is deeply tied to personal experience and informal storytelling. It cannot be used as a noun to mean 'childhood' in the way that 童年 functions.
