Old people, children and women earn the most money, which can be said to be one hundred for one investment.

1. Money for the elderly. Old people don't care about food and clothing, but they are most concerned about health care. They all want to live a long life. As long as they can stay healthy, they can live a long life. For the elderly, money is not a problem at all. If you have a good regimen, or you recommend a good regimen to the elderly, these are all ways to make money. I don't need to tell you this example. Look at the fitness clubs all over the street, all kinds of nourishing and nutritious health products, and all kinds of free health courses. They all stared at the old man without exception.

2 female, plastic surgery, self-cultivation and slimming; Women care most about their appearance. From an 80-year-old woman to a few-year-old girl, their love for beauty is constant! Especially some women in the city, for the sake of beauty, do not hesitate to cut their bodies. If you have more female customer resources. For example, you are a friend of women's clothing, cosmetics, mothers and babies, beauty merchants and the media. As long as these people still trust you, you can act as an intermediary agent and introduce customers to plastic surgery hospitals. The general commission ratio is around 50%. As long as you succeed in a few orders a day, even a single income is not cheap. Don't forget that a face-lifting needle costs thousands of dollars, and a double eyelid costs thousands of dollars, let alone breast augmentation. This profit is scary. Of course, the intermediary business of medical beauty does not mean that it is not difficult at all. In addition to the resources of female clients, you should screen out reliable plastic surgery hospitals or reliable surgeons, otherwise people will easily argue with you if they are dissatisfied. That's all that matters. After all, what we are doing is not a one-time transaction. More importantly, there is basically no investment in doing this. A mobile phone wastes some traffic charges and your feelings. You have to impress each other and make others believe in you in order to succeed. As for other inputs, you don't need them at all. It is particularly convenient that if you don't want to do it at that time, or for other reasons, you can stop at any time, without looking for a store or investing money. The only hard thing is to keep your mouth shut, talk more and say more nice things!

3. Children's cause: It's easiest to earn money from children. One is to open a shop or buy baby food "milk powder". Then there is child care and training. Every holiday, parents with children are worried and don't know how to arrange their children's lives. You can start a custody class, and the income is ok, but the investment is a bit large.
