What companies do system integration and network engineering in Tangshan?

There are not many system integration and network engineering companies in Hebei, only a few, and even less in Tangshan. I only know Tangshan Weir Electronics Co., Ltd..

Of course, this is a company specializing in system integration and network engineering. Some companies don't focus on this, but it involves, for example, that any bigger company will have its own website. Does the server of the website need to be maintained by a network engineer? This belongs to this kind.

For another example, there is a classification item in system integration-weak current system integration for intelligent buildings, and there are many, dozens of them. Let's talk about Jixing Kaiyuan, Chuangji, Huayan, Yintong, Shi Sheng Evergrande, Dawei, Jiaan and Jardine Matheson.
