1. Variations: According to the layout of the opponent's left gun, try different variations to interfere with the opponent's deployment and make mistakes. You can consider adjusting the position of the car, or leaving a space between the car and the soldiers to increase the difficulty of the other side's operation.

2. Car-gun coordination: first arrange your car in a proper position, and then guide the opponent to move the half-way gun to a certain position, so that your car-gun can cooperate with the opponent's car and horse to control the rhythm of chess.

3. Coordination between soldiers and guns: When soldiers are on the elephant's eye or clogs side, they can use clever coordination to dismantle the defense of the other side. You can push the soldiers one step forward, form an array in front of the gun, threaten the other side's horse or car, and force the other side to take defensive measures. Artillery can also support each other and disturb each other's cars and horses.

The above strategies only provide some ideas and need to be adjusted according to the specific situation when playing chess. In addition, mastering these skills and strategies requires more practice.
