All the foreign experts who came to visit were shocked and surprised. At that time, in recognition of Zhan Tianyou's achievements, an American university decided to award him a doctorate in engineering and invited him to attend the ceremony.

But Zhan Tianyou was responsible for the design of another railway, so he resolutely declined the invitation. His spirit of serving the country rather than the individual has won praise at home and abroad.
