My company just bought laser engraving when I won’t use it, but because I just went to the company and my colleagues were not very familiar with them, so I was embarrassed to ask them, it was my time to eat at noon to go to laser engraving on the other side of the study and then on the Internet, Baidu, finally finally understand the laser The operation of engraving. Then one time in laser engraving, I found out that many of the colleagues would not use it, and I taught them how they were happy to receive their thanks. It’s good to be able to share what you have learned to others and learn to use now. It’s no wonder that many famous people are particularly advocating that they are old and learned, and that the feeling of progress is good.
