Maybe you can help them fix it. While you're at it, please help the Russian designers and the Western designers out too. The middle east is filled with the corpses of their tanks. Maybe you can also help the Indians build a tank that actually balances mobility and protection. Seems like their Arjun mk2 copied this turret geometry.
On a serious note, PLA tank doctrine is frontal armour heavy. They don't anticipate being flanked from any direction. To be honest I don't think PLA even bothers with tanks now that UAVs can knock out entire divisions with ease. Wasted lives and material.
I wouldnt call 30 degrees off centreline flank.
