When I was in the first year of high school, I just stepped into the company. I didn't know the operation of many machines. Whenever I set the parameters, I was very confused and I had to learn from the master. Until now, I have been in college. I have been in the company for three years. Almost all the operations of the machine have been learned. I can also teach the younger how to operate the machine and how to produce a good product.
