In the unit, it is better than other science and engineering, and the work is easier.
If you want to make money, you can do it yourself. I know many people who have worked in enterprises for seven or eight years and do it themselves. Generally, they sell refrigeration accessories or equipment or do maintenance.
On the whole, it's not bad.
It is thermal energy and power engineering. The heat and cold of this major largely depends on the national energy policy. Judging from the general environment in recent years, it is still good, and the employment situation is relatively optimistic. It's not true that this major rarely recruits people at job fairs. Maybe it's just the situation around you, but the situation around me is just the opposite. Many people recruit this major at the job fair.
