As the saying goes, "it's easier to start than to do well." Print shop has three points: 1, suitable port, 2, comprehensive technology, 3, flexible management. With these three points, I think you can do it.
In fact, the investment is not big, about 3W is enough, the operation needs to be from point to surface, and the development can be gradual. Which printing shop has not been open for more than ten years.
The principle of doing business depends on the direction. Stick to it, stick to it, and stick to it! ! Always succeed.
