Air conditioning installation group name

What are the WeChat groups in industries such as machinery processing or machine tool repair and processing? I did n’t sell it in this way. There are a lot of new days. Who can share a few for me? Do not advertise! Intersection thanks

How to automatically push messages to the group in the group? I want to send the editing content automatically to the group chat at 7 o'clock every day. Can the company's WeChat be realized? Do not use group chat robots. If the company's WeChat does not work, is that three -party software?
