Ordinary technician Lin Yaozong, withstanding the incomprehension of those around him, used his own funds to purchase an old-style punch press pending scrap, carefully repairing and maintaining it.

This old machine, ignored by everyone, solved the problem with its unique process advantages. New and old equipment worked collaboratively, and everyone worked together with one heart to successfully complete the production task.
