In the photo, the company's team members are posing with their "old partner" - the machine that has been with them for several years. Some people quietly patted the polished control panel of the machine, while others had oil stains on their fingertips from just finishing maintenance. At the moment the shutter was pressed, the smiles on everyone's faces were particularly genuine, and their eyes and eyebrows were filled with familiarity, as if silently reminiscing about the days when they worked together and solved problems together, hiding countless little moments that cannot be told.
