These two schools are similar in strength, and both have doctoral programs in municipal engineering. Hehai Municipal Government focuses on the direction of water conservancy, while Tianda Municipal Government focuses on the direction of water treatment (chemical industry), each with its own advantages.
In addition, Xi 'an University of Architecture and Technology is also very good, and its strength is definitely above the above two schools. The only disadvantage is not 2 1 1, so it is not too difficult to test, and the cost performance is very high.
