As a permanent member of the United Nations, why are there more women than men in Britain, France, the United States and Russia?

This may be related to history and culture. Historically, wars in the past were all aimed at plundering wealth and beautiful women, while Britain, France, the United States and Russia were all invading powers. They plundered women from other countries, and there were many casualties among soldiers in the war, so their proportion of women was very large. China, however, is a country invaded and plundered in modern history, and the traditional preference for sons over daughters has also aggravated this imbalance, so the proportion of women in China is very small. As far as life is concerned, it is reasonable to have more women, because women live longer, so this structure is basically balanced. Unbalanced structure will lead to social problems, affect development and strength growth and national rejuvenation. On the other hand, a high proportion of women is conducive to social development, and the cost of winning a spouse will be low. Men can devote more energy to the cause of national construction. Unlike many men in China who are stumped by the sky-high bride price, it is hard to imagine that they will consider making their own creative contributions to the country's development.
