Why is the CRH5A called a donkey?

[StDakota]

CRH5A is called a donkey because its front shape was nicknamed "5 Donkeys". Exterior dimensions: The C5 is 3.2 meters wide, 4.27 meters high, with the leading car being 27.6 meters long and the intermediate cars being a standard 25 meters long, totaling 205.2 meters in length. Each traction motor has a power of 550 kW, with a total of 10 motors per train set, providing a combined power of 5500 kW. The maximum operating speed is 250 kph. To accommodate low-platform stations, the outward-opening sliding doors extend from approximately 500 mm above the rail to about 3300 mm above the rail. Bidding proposal: The "5 Donkeys" was the proposal submitted by France's Alstom during the bidding process. At that time, there was little interest in articulated trains and tilting trains, and Alstom's French headquarters only knew how to build articulated trains. Therefore, Alstom turned to its Italian division, Fiat, to come up with a proposal.
