It's going to take a long time to translate.
And I haven't watched the entire video yet.
But to summarise, it says that this particular 4th gen tank will only be 30 tons in weight. A Yu-20 can transport 2 of them. It will have a remote turret like the Russian T-14. In terms of protection, the tank may have used the recently reported new-generation titanium alloy for its armour as well as new-gen ERA. The main armour itself may only be able to defend against small calibre cannons (like an anti-air artillery). The crew protection module can defend against shells from a 105mm tank gun. It may be insufficient against 120mm and 125mm tank guns, but that's what the reactive armour is for.
It also has a separate armour module dedicated to protecting the crews,
An active protection system is installed to counter the drones and anti-tank missiles.
For high-velocity anti-tank rounds, it will rely on its sensory, datalink, and fire control system to achieve first-seen-first-shot.
The main armament may be the new 105mm Electrothermal-chemical cannon with very high accuracy, so it can be shot from a distance where the enemy 120mm tank gun cannot achieve the same accuracy.
In terms of mobility, they aimed to make it the most agile tank in the world.
The tank also emphasises stealth against radar.
