[Explanation] Every day I go out early and return late, working at a depth of 2 meters, and I am often infested by mice and mosquitoes...

  Kang Keming and Han Shaoshuai, who work in a heating company in Changchun, Jilin, are a pair of "masters and apprentices" responsible for pipeline maintenance.

Young Marshal Han, a "post-95" young man who has just joined the post for one year, must master the maintenance technology and experience in the one year before Ken Keming's retirement, so as to ensure that he can successfully take over the "baton" in the hands of the master.

  This November holiday, they stick to their posts and prepare for the upcoming heating season.

  October is the peak period for repair work on heating pipes.

Kang Keming and Han Shaoshuai have to maintain the 200,000 square meters of heating pipes they are responsible for before the middle of the year.

In particular, the pipelines in old communities have both aging problems and relatively poor working conditions.

  The first time I went to the ditch, I was very scared. There were mice and mosquitoes in the ditch. Master told me that this is the (common) working environment, and it will be the same in the future.

  [Explanation] Shaoshuai Han, who has gradually adapted to the working environment, is now the "main force" in the maintenance front line. Many basic maintenance work is undertaken by young people such as Shaoshuai Han.

  According to Han Shaoshuai, they often work in claustrophobic environments such as 2-meter-deep trenches and narrow tunnels, and they also need the guidance of a teacher in complex situations.

  Like me, the stature is relatively large, the gutter is relatively small, and it is more difficult to go down.

The trenches are relatively humid and the space is relatively small.

  [Live] Just hold it tight, (hold it tight) Yes, hold on, okay.

Sometimes the pad gets old over time, and it is prone to dripping, leaking, etc. After it arrives, slowly tighten it if it can hold tightly, and if it can't be tight, you need to change the pad.

Before heating, we must check the places that should be checked when we press and test the water. If we find any leaks, we should deal with them in time.

  [Explanation] In the underground space, Kang Keming is trying his best to impart his more than 20 years of work experience to the young man in front of him.

  Since 2001, Kang Keming has been doing the work of "giving help in the snow" for the citizens.

From burning coal to interconnecting heat and power, heating technology in cities continues to improve, but plumbing maintenance jobs still need someone to stick to.

  Although our current smart heat network has relieved us a lot (burden), because our community is more than 600,000 (square meters) in area, it is an old community, so the pipe network is very old. It is necessary to press and test the water, so it needs to be checked and repaired manually.

Therefore, we need young new forces to join our industry and work together with us.
