What is the future of hydraulics? Where is the hydraulic pressure recruited?

The prospect of hydraulic pressure is better, and it will certainly develop greatly under mechanization. If you want to recruit, there will be a need in general construction machinery factories, but at the same time, other industries such as coal mining machinery, petroleum machinery and ships are all useful. Such as Shijiazhuang Coal Mining Machinery Co., Ltd. and China Coal Zhangjiakou Coal Mining Machinery Co., Ltd. But I'm not sure who I need now.
