What does "muddling along" mean?

People are used to slacking off their work and not working hard, which is called "muddling along". The so-called "grinder" originally refers to a process of building engineering, that is, grinding the surface of brick walls, which is equivalent to the decoration of pointing and grinding stones now.

This process seems simple and doesn't require too much physical strength, but it actually requires meticulous manual work and takes a lot of time to avoid worry and recklessness. As for the connection between "grinding machine" and "foreign country", there is such an interesting story.

From 19 17 to 192 1, the United States used the "boxer indemnity" of the Qing government to build the Union Medical College and the Union Hospital in Beijing. As this project was funded and designed by foreigners, China workers called it "foreign workers". Union Medical College Hospital has 14 main building and high-rise building, and the process of "grinding" is very complicated. Therefore, many workers who take part in construction projects call this process "idleness" to express their dissatisfaction with the criminal acts of western imperialism invading China. Up to now, the word "muddling along" has become the meaning of not being active at work.
