This can be quite a perplexing issue for all English speakers.
In English, you can immediately tell whether the subject is male or female based on the pronouns 'he' or 'she.'
However, the fact is that even native Chinese speakers can't tell whether the subject is male or female without context.
Chinese speakers also ask the speaker, 'So, are you talking about a male or female?'
Therefore, next time you encounter this issue, feel free to ask the speaker directly,
'Are you talking about a male or female?'
Native Chinese speakers do this too, so there's no need to worry—just ask!"
