Although there is no strong data to determine whether this is related to the Japanese-Qing War at that time, there are several statements for reference.

1. Wheat flour as a raw material at that time relied heavily on China (Qing), so it was named

2. Just after the Japanese-Qing War, the victory of Qing was as incredible as that of a mouse defeating an elephant in Japan at that time. The chicken in the whole country moved, so it was changed.

So personally, I think it may have something to do with the Japanese-Qing War, and it is also possible to commemorate it.
