This kind of chess has several characteristics, which are different from ordinary chess.
First of all, the chess I invented is not a single piece, but a small model of various shapes. For example, a car is a chariot, a gun is a cannon, an elephant, and a handsome general. This model makes people like it at first sight.
Secondly, these models are voice-activated, and they will only move when you give an instruction. If you want the car to attack the enemy's handsome, you must make it clear that the car will automatically eat the handsome if it understands the instructions.
