The protagonist Zhang Lei is a native of Decheng City, Linhai Province. He graduated from a college with a major in electrical automation. After graduation, he took root in the front line of Donggang Petrochemical.

He led the electrical repair team to overcome difficulties and successively solved a number of major electrical equipment faults that restricted production. Subsequently, he represented the company in the district-level, municipal-level, and Linhai provincial-level maintenance electrician vocational skills competitions. He passed all the tests and won the first prize in the provincial competition. He has steadily grown from an ordinary electrician at the grassroots level to an irreplaceable core technical backbone of the company, interpreting the original intention, perseverance, and craftsmanship of grassroots industrial workers in the new era.
