What about Langfang Hamamatsu Photonics Company, its working environment and treatment? Do you have any friends who work there?

It's hard to meet someone who knows you and is willing to answer your questions. If you have the opportunity to go to the company for an interview, you can learn more about the working environment and the working face of employees. It is best to talk to employees alone or ask people around the company, such as doormen, security guards, shopkeepers, etc., on the pretext of wanting to know the actual work content. This information is more objective and true. Everything is true only if it has been experienced. Good luck with your work.
