In the summer of more than two thousand years, Xiao Zhang graduated from university, with full of enthusiasm and infinite longing for the mechanical and electrical industry, and resolutely joined a well-known mechanical and electrical equipment manufacturing company. He has been obsessed with various mechanical and electronic devices since he was a child, and he has accumulated a wealth of theoretical knowledge during his university years, and he firmly believes that he can shine in this industry. 

However, the huge gap between dreams and reality soon gave him a dismount. Xiao Zhang found that the masters in the workshop did not welcome his arrival. He wanted to learn more about the equipment by looking at the drawings of the equipment, but every time he asked the master for advice, they were always vague and sometimes even deliberately gave wrong information.

Once, Xiao Zhang took the drawings next to the equipment and studied them carefully, trying to understand how they worked. A master came over and said disdainfully: "Young man, reading books is useless, practice is the most important thing." Xiao Zhang was dissatisfied, and he responded: "But theory is the foundation, and only with theory can we practice better." The master sneered and turned to leave. 

Xiao Zhang was not discouraged by this, and he began to use his spare time to study various professional books, trying to make up for the shortcomings in practice through self- study. Whenever he solves a technical problem, he excited ly runs to the workshop to verify his theory. However, the masters always scoffed at his achievements, and sometimes even deliberately found fault and questioned his ability.   

The picture above shows a corner of a state-owned factory in 2000, don't believe it, it's really like this. 

One day, Xiao Zhang found that there was always a problem with a key component in the equipment, and he found the root cause of the problem by studying the drawings and consulting materials, and proposed a practical solution. However, when he told his master about his findings, they seemed unimpressed. One of the masters even sarcastically said: "Yo, college students are different, you can see the problem by reading the book." Xiao Zhang felt very uncomfortable after hearing this, but he firmly believed in his judgment.  

Finally, there was another problem with the equipment, which happened to be the problem that Xiao Zhang had found before. This time, the masters were helpless with their own methods, and at this time they had to use the method Xiao Zhang said before, but th would not say that this was the method Xiao Zhang came up with, not to mention that in front of the leader, even when facing Xiao Zhang alone, they would not say that they were using Xiao Zhang's method. Don't believe it, sometimes the workshop at that time was so thick and dark. 

At that time, Xiao Zhang still didn't realize that although these masters were experienced, their knowledge system was outdated and lacked the motivation to update and improve. What's worse is that they sometimes pretend to be confused...... To be continued
