May I ask the origin of the word "sissy"

We should start with the meaning of the empress.

Empresses, empresses and concubines in ancient palaces are all called empresses. These aristocratic queens all speak with a pinch of accent, which makes the tone of women who are already more soothing more sour. So it is derogatory to say that some women are sissy.

Because not all women's speeches or mothers' speeches are sissy, we should not call sissy "feminine" or "sissy".
