Take a walk around SEG Computer City on Yanta Road, and you will find all these devices. If you want to live broadcast outdoors, you can buy a mobile network terminal and connect it to your laptop.

This also requires a battery, an inverter wireless microphone and a matching receiving port. I have seen professionals use small gasoline generators for live broadcasts. It depends on whether you are doing it on a large or small scale, indoors or outdoors for a long time.
