In the late Qing Dynasty, the steam engine entered China, but the vast majority of Chinese at that time did not know what it was, and few people in the imperial court understood the significance of this machine, so Li Hongzhang gave a fold, introduced the action principle of the steam engine and its role, and wrote in the compromise:

The machines of boring wood, eye-punching, twisting and spinning, and casting bombs are all twisted in the steam furnace, filled with water and blazing charcoal, the water is boiling and full of gas, and the opening is reached by the copper throat into the gas cylinder, and an iron pillar is connected to the cylinder in the cylinder, and the iron wheel is lifted and tilted with the air, and the wheel is rolled with the belt, and the axis is tied, and the rotation is rotated, and the rotation is maneuvered, and only the manpower is used to make a longitudinal, not relying on the movement of manpower.

This is actually a popular science article written to the imperial court on the steam engine, which shows that Li Hongzhang was indeed a bureaucrat with a broad vision in that era, much more enlightened than those who could not eat the ancients.
