There is also a high wall, which feels very dangerous and fragile, and no one dares to approach it. High walls are used for isolation. If they become a circle, they can protect the people inside, or they can bind the people inside and not see the outside world. If it's just a wall, it's insurmountable. It is said that this wall is dangerous and thin, which shows that this artificial wall forgot to increase its thickness while trying to increase it. You don't need too much material to build a high foundation. The higher it is, the harder it is for people to cross, and you can achieve the effect of rapid isolation. However, the foundation of rapid prototyping is not solid enough to stand the wind and rain, the sun and rain, and the test. Things that are eager for quick success and instant benefit can achieve the desired effect in a short time, but once they are shattered, they will hurt people who once trusted that wall in their hearts.
The water tower is useful and reliable, and can be replaced and blasted. And how long can a thin high wall last? It may even do harm to people around it, because it is high and may spread to a wider range. Because it is still standing, I don't know when it will fall, which will make people panic. Without going to the water tower, you can be far-sighted and stand far away. Water towers and walls are man-made buildings and can be of practical value. They must be safe and reliable in use. When people no longer need it, they can take the initiative to tear it down. There is no doubt that this high wall will be built as high and fast as possible, but the quality is not guaranteed and it cannot be trusted by people. People are both suspicious and afraid of this.
In fact, whether this wall is high or thin is a gamble on the dreamer's worries and fears. If the dreamer feels safe, then this wall can be generous and extremely safe. I'm worried that this wall is not stable enough to hold on, and I don't know when it will fall down and hurt myself.
