Yeah, I noticed that straight off.
Compare that to a 75-year-old Russian tank: 
Nice vertical surfaces on that one.
“Nice vertical surfaces on that one.”
That’s reactive armor on the turret. It may be advanced enough that it is the main armor making the tank substantially lighter. There are advantages and disadvantages. Also, I suspect the Chinese are not as concerned with crew survival as they are with overwhelming the enemy with numbers. As Stalin said, “quantity has a quality all its own.” This approach is probably a tradoff in cost vs. survivability. We’ll have to wait for a war to see if they got it right.
That was my first thought...maybe it is layers or reactive armor or something like that?
