If you can't earn 100% in business, you have to run it on your own. In the same business, some people make a lot of gold foil, and some people lose everything, all of which are caused by different management methods. Of course, it is also important to choose industries and projects. Choosing a good project is at least half the battle, and the rest depends on how you manage it. Gold recycling is a good choice, with stable market, high profit and low competition. This industry used to be difficult to enter, and it was mostly passed down in the family, so it was difficult for outsiders to enter. Therefore, there are not many people who have been engaged in it since ancient times, but those who have been engaged in it have made money, otherwise it will not be circulated for so long. Although there is no guarantee that everyone who has done it will earn a lot of money, as long as you work hard, you will earn more and earn less, and you will never lose money.
