How to distinguish between physical injury and magical injury in Dream Three Kingdoms?

The general skill is magic damage, and the general attack is physical damage. But not necessarily, for example, Cao Hong and Da Qiao W are ordinary attacks with additional magic damage. Cao Pi, Sun Shangxiang W additional absolute damage. Another skill damage is physical damage, that is, calculating hero armor. The higher the armor, the less blood will be lost in this kind of injury. Magic damage is calculated as the hero's spell resistance. The higher the spell resistance, the less such damage. In addition, there are percentage deduction, direct deduction of fixed blood value and so on. You'll know when you play too much.
