Why can't you talk about yellow and color when chatting with women?

Because women are more reserved than men, they have come to a bad end since ancient times, such as Pan Jinlian, who was less vilified by Ximen Qing. This is caused by the traditional differences between men and women, so in some social occasions, women are not used to saying yellow and color.

Women and girlfriends occasionally do it, and those are yellow topics between women without men.

But if a man talks about yellow and color in front of a woman, it will probably be considered disrespectful.

Respecting women is a traditional requirement and the most useful form for women.
