Dr. Tsinghua is not overqualified as an electrician, and his skills are excellent. Electricity is dangerous. You can't be an electrician without a little skill, and the ability to master a lot of electrical knowledge as an electrician is beyond the reach of ordinary people. It is true that frontline electricians are not well paid, but people have to undergo special training. If people with high academic qualifications do it, it may not be a waste of talents, but it may be an exercise. Everyone should have this exercise opportunity. In fact, no matter how talented people are, they can't be considered overqualified to do small jobs. This shows that a person's persistence is not afraid of suffering. Indeed, there are not many people who can bear hardships today, and there are not many people on the front line. I know many people don't think highly of the first-line electrician position, but I think it's quite good. After all, electrician is a very practical job. And no one can use electricity. Therefore, the post of electrician is necessary and everyone needs it. Therefore, even Dr. Tsinghua is not overqualified, but an experience and a gift.

There are people who can't be first-line electricians. Although many people don't like to do this major, some people can't. After all, they should have certain professional skills. Electricity is a high-risk industry, and not everyone can do it, nor can they do it if they want to. Requires a certain degree of operation and electrician ability. Therefore, not everyone can do it, and they need ability.

Therefore, I think that Dr. Tsinghua's willingness to be a first-line electrician is not overqualified, but an exercise, a self-exercise, and a growth!
