True to the intention of the Workers' Party of Korea to dynamically conduct the high-speed tunneling movement at the complex, the shock brigade members overfulfilled their yearly tunneling plans every year by displaying the undaunted spirit despite the difficulties caused by global health crisis and natural disasters.

During the high-speed tunneling movement they have grown to be the patriots who are dedicating themselves to the prosperity of the country and the personifiers of the collective spirit who are devoting themselves to difficult and toilsome work while helping and leading each other forward. This is another precious success made by the vitality of the revolutionary mass movement.
