What is the prospect of learning hydraulic and pneumatic?

Hmm. I also study mechanical manufacturing and automation. When I chose the direction in my junior year, I chose hydraulic pressure. At that time, many students studied metallurgical machinery and mechatronics. Now I think it is wise to learn hydraulic pressure, which makes it easier to find a job. Many foreign companies also need such talents. In fact, there is little difference between hydraulic and pneumatic principles, and it is not too difficult to learn pneumatic after learning hydraulic. In modern machinery, a lot of knowledge about hydraulics, pneumatics and electric control will be used.
