I majored in thermal energy at He Gong University. I don't know if you are a freshman at He Gong University. Don't come to Hegong University for postgraduate study. I regret it when I was admitted to He Gong University as a freshman. Thermal energy is a key subject for upgrading, and it is not bad to go back to Hebei for employment, but the salary is around 1500, and many people have signed it. One of them has been actively preparing to find a job this year. But most of them are power plants and boiler rooms, and there are basically no power plants in the best direction. Going there is also the dirtiest job that no one likes to do. The direction of internal combustion engine is better than thermal energy. Three books are unclear.
