Introduction to the Fireworks Pond: When you enter the gate, you will see a large courtyard with a pool on both sides of the corridor, which is called the "Fireworks Pond". In the event of a fire, one of the methods is to collect water from the fire pit to put out the fire and to block the fire wall, but the biggest feature is that it is located above the roadway. Because the designed width is only about 80 centimeters, in the event of a fire, people only need to support the high walls on both sides of the nearby laneway to go up to the roof and lift off the tiles to cause the flames to jump up, thereby cutting off the fire path and preventing the spread of the fire.
