Dahua has a new infographic. Such marketing material is not uncommon but it is almost always about company specific metrics.

My guess is that they are measuring this from when their founder started in the industry, not their company, but that too is strange since the document is called 'Dahua by the numbers'. That or they are really bad at math.
One document alone means little but combined with their ongoing dysfunctionality this gives insight into a mentality more focused on praising their founder than communicating their value to customers.
