War is one of the reasons for this situation. Vietnam was once a French colony in history, which is also the reason why Vietnamese local men are lazy. Women, on the other hand, are more tasty and hardworking. However, Vietnamese women are generally inferior to men in social and family status. Especially in some relatively backward village communities, women are the tools to carry on the family line and the economic pillar of the family. They should not only educate their children at home, but also bear the financial burden of their families. They have to undertake a lot of farm work at home, ploughing fields and carrying hands, all of which they have to do.
Men ride motorcycles all day and run around, feeling ashamed to go to work in the factory, so they don't go to work, drink tea all day, let their wives go to work all day, and even sit at home and wait for opportunities to "do great things", "be a big boss" and "make a lot of money". Vietnamese men's sense of dignity is far greater than their sense of family responsibility. They feel ashamed to go out and set up stalls and do some tiring work, but they are not qualified to do well-paid and decent work.
However, not all families are like this. Some men, such as China, are struggling to support their families outside. It can only be said that some people are lazy and some people are diligent and capable.
