Opening slogan of hydraulic press

The word "refueling" comes from Northeastern University funded by Zhang Xueliang. It should be in the 1920s and 1930s.

Refueling literally means adding fuel or lubricating oil to a running machine or car. The broader usage is to encourage and support others, to give others an encouragement or encouragement, which is the most commonly used word in life.

"Come on" is the labor song of the oil press workshop. Several people shouted their trumpets, and as a bell rang, the squeezed oil was added to the oil container. Come on, this is a repetitive process, because you have to work hard to come on. It's not what people often guess at random. Is it because people add some oil to each other first that people have strength? No matter how the author came to the conclusion, this explanation is not forced.

In detail, the traditional oil pressing technology is to bake, grind and steam raw materials such as peanuts, sesame seeds or camellia seeds to make cakes, and stack a plurality of cakes vertically and horizontally in a wooden pressing groove, and then insert wooden wedges into the right side (or both ends) of the groove one by one. Wedge insertion is a hard job. Generally, it takes several people to hold the rope, the hammer handle or the hammer body, which is a bit like ringing a bell and hitting a wooden wedge forward with a hanging stone hammer or wooden hammer. This action is also called bumping into oil. At this time, everyone or clappers will shout their songs, such as "one, two, three, come on" and "come on, don't cough". The hymn of hitting oil varies from time to time and from place to place. More importantly, the meaning of "refueling" is unreasonable (it should be "wedging" or "bumping"). Therefore, as soon as this poem came out of the oil mill, the original intention was forgotten and there was no way to guess.

Don't forget: the cheering slogan of this sports field was also a cheering slogan before it was transplanted from the oil mill. In this simple, warm and loud cry, the simplicity and cheerfulness of the working people in China continue.
