This is a passionate story about youth and struggle. A group of energetic young intellectuals bid farewell to the bustling city and went to remote mountainous areas to devote themselves to the construction of a red, orange and indigo factory. In this desolate land, they shed the sweat of their youth, used their dreams as horses, and were not afraid of hardships. Faced with the harsh natural environment, simple living conditions and complex technical problems, they did not flinch at all and moved forward hand in hand with the spirit of unity and friendship. During the day, they were busy on the construction site, contributing their wisdom to every aspect of the construction; at night, they sat around discussing future plans and looking forward to the prosperity of the factory after its completion. Their youth shined the most dazzling light in this vigorous industrial construction, composing a passionate song of struggle.
