Small zipper, great learning, how big is learning? According to the current situation, zipper involves nearly 20 subjects, such as chemical industry, machinery, electronics, automatic control, textile, metallurgy, printing and dyeing, etc., there are many categories and a wide range of knowledge. How deep is the knowledge? At present, there are more than 25000 zipper patents that can be queried from seven countries and two organizations in the world, and more than five thousand zipper patents have been applied for in our country. In the last century, zipper was appraised as one of the top ten inventions that have the most influence on human beings. Zipper has been constantly innovating and enriching for more than a hundred years. Up to now, no product can replace the function of zipper. Some people even predict that zipper can be replaced by zipper. Zippers are unlikely to be replaced in the next fifty years.

I have been working in zipper industry for 35 years, and I have always been in awe of zipper. Zipper has a long and complicated production process, has high precision requirements, is the integration of many specialties and types of work; zipper varieties have nylon zipper, metal separation zipper and so on, the scope of application is very wide, there is a deep professional knowledge, to do a good zipper is not an easy thing, zipper can not be made casually, this is not my own feelings and views. How on earth should a zipper involving a lot of learning be made? Or how should we make a good and valuable zipper? it's worth pulling in China. Chain people think about the problem, we can not stay on a superficial level, replication is not representative of creation.
