[Explanation] In late February, Changchun, Jilin Province, gradually warmed up, and motorcycle enthusiasts drove for a trip.

Liu Jingcheng also started to get busy.

  51-year-old Liu Jingcheng started learning to repair locomotives at the age of 13. So far, he has repaired nearly 10,000 motorcycles and thousands of heavy locomotives.

  On February 27, the reporter walked into his repair room and was full of heavy locomotives to be dismantled and repaired.

He and his son Liu Shuai were busy repairing a Harley-Davidson motorcycle.

  Liu Jingcheng told reporters that the premise of being an excellent "motorcycle doctor" is to be able to drive, listen to sounds, and understand the performance of motorcycles.

When he was young, he often traveled far by bicycle with his friends. Xinjiang, Ningxia and other western regions of the motherland are the places that everyone yearns for.

  The furthest I accompanied two Germans to Xinjiang, they arrived in Kashgar, and from Changchun to Kashgar, I went around and came back for 43 days.

  [Commentary] Liu Jingcheng said that his son has shown a strong interest in motorcycles since he was a child, and now he has become his right-hand man.

  The father and son often share their work routines on short video platforms, which are welcomed by many fans.

Gradually, locomotive enthusiasts from Inner Mongolia, Liaoning, Heilongjiang and even Guangdong contacted Liu Jingcheng one after another, and they were very confident in transporting the car over for him to repair.

  Liu Jingcheng introduced that repairing heavy locomotives is becoming more and more "scientific and technological", not only requires "craftsmanship", but also knows how to operate a computer specially connected to the locomotive system.

He is good at using tools, and handed this problem to Liu Shuai.

  These imported motorcycles involve some more professional motorcycle-level application software, including some foreign languages, mainly English, and (and) some controller codes.

  [Commentary] At present, Liu Jingcheng and Liu Shuai mainly repair some imported heavy locomotives. Liu Jingcheng is used to using tools, and Liu Shuai helps his father operate an all-English computer in his spare time. After several years of continuous learning, he can operate it with ease.

  Although motorcycle repairing may seem like a hard job in the eyes of others, in my dad's heart, every time a car is repaired, there is a sense of achievement.
