Why do some people who do structural design always complain, while others are trying their best to get into this industry?

1. In fact, those who engage in structural design have to work in the office all day long, which is quite hard and very tiring!

2. After structuring people complete a project, they will be on tenterhooks all day long. It’s not that I’m worried about my miscalculation, but I’m worried about whether the construction quality can reach the state of the stress model I assumed!

3. People who have never engaged in structural design will see this: Sitting in the office all day, usually "can't get out of the door, can't step out the second door"! It couldn't be more comfortable!

4. What is said in "The Besieged City": People in the city are vying to get out; people outside the city are vying to get in! That's what it's about.
