Choosing one thing in one's life, Dunhuang guardians race against time, taking research and protection as their lifelong career and pursuing without regrets. Some regard Dunhuang as a spiritual life, some firmly say that if they come again, they will still choose the Mogao Grottoes, and some think that they can protect the Mogao Grottoes for life without regrets. Many researchers have been rooted there since their youth, and they are still determined under difficult conditions.

Wu has lived with the steam turbine for 42 years since 18 years old. These 42 years coincided with the deepening of reform and opening up, which made his fate with the steam turbine and rewritten his life. Today, with only a junior high school education, he is already a senior locksmith technician with a national master studio.

Historical background:

1979, Wu started his apprenticeship, just in time for the system reform of state-owned enterprises. "The most direct manifestation is the salary increase. According to the level, increase 5 yuan to 7 yuan at the first level. " Wu Shuo, the contract system has aroused everyone's enthusiasm, and the factory has begun to study technology. "We have four or five people in a dormitory, and we often take the drawings back and stay up late to study. However, some German translations are not in place and can't be understood. We will discuss them together the next day. "

The mysterious world inside the steam turbine is far more complicated than Wu's initial imagination. "The accuracy is very high, and the manufacturing error should be controlled within three filaments, which is equivalent to half the thickness of a hair." Wu Shuo, sometimes the strength of a screw is different, and the result may be completely different.

What impressed him was that there was a small problem with a steam turbine at that time, which was solved after 13 consecutive trial runs.
