It takes free time to research and develop new production technologies. If an employee is only busy working all day long, then the employee’s skills can only be improved by the ones he is currently doing. Employees will not improve on other seemingly unrelated abilities, or for those who have not yet seen the benefits, on the one hand, many people do not have the need or desire to improve, and on the other hand, employees simply do not have time to learn or think about new things. For example, why is it that the same foam engraving process, the rounded corners we make are excessively smoother and more natural? And many people will have jitter pits? Why is it a vibrating knife to cut, why do some people can cut the curve smoothly, while most people need to polish it manually? It is very obvious that people who do well spend time and cost to research, as for how to achieve good results? Take your time, put your energy.
