I graduated in 2007, majoring in chemical engineering, environmental science and engineering and hydrology. Hydrology is not the strongest major in Chang 'an University, but it is definitely not weak. Your major is one of the only two academicians who have grown up, and it is the only one who has been trained by himself, not by money. Think about it. This major is better than domestic hydrology major. Employment is also stronger than environmental engineering, and the environment is better.
