Which is better, the Academy of Iron Sciences or the Fifth Institute of Iron?

The Institute of Iron Science and the Fifth Institute of Iron Science should not be directly compared. The full name of Tiewuyuan is China Railway Fifth Survey and Design Institute Group Co., Ltd., which is a subsidiary of China Railway. China Railway is a central enterprise directly under the Ministry of Communications, so Tiewuyuan is also a central enterprise. As the only multi-disciplinary and multi-professional comprehensive research institution of China Railway, Railway Science and Technology Research Institute has developed into a large-scale scientific and technological enterprise integrating scientific and technological innovation, technical service, achievement transformation, consulting and supervision, testing and certification, and personnel training.
