How to understand the local killing terms in Chess Wizards?

A car blocking two strategic arteries at the same time is called a car blocking the second line. It can also mean that the car controls the second horizontal line counting up from the original position of the commander-in-chief, or does not display the head of the other commander-in-chief, or protects its own commander-in-chief and prevents the other troops from advancing.

Your coach (general) is sitting outside, cooperating with a car or a soldier to assassinate, and the other party can't recover. This is called exposure and killing.
