PLA heavy machine guns

Hopefully I am posting this in the correct forum. There doesn't appear to be any information on heavy machine guns in service with the PLA either on this site or the other popular sites covering the Chinese military. Heavy machine guns such as the ones mounted on tanks and FAVs, or on tripods for WWI style air defence.

Does SinoDefence plan on having this coverage sometime?

Does anyone know of sources of info on this topic on the web somewhere?

here is machinegun gun section on sino defence for some reason its not in the ground forces page anymore but it is still on the site map
