At six o'clock in the morning, Dongjiang City Railway Station was shrouded in mist and noisy people. The huge electronic screen scrolled with train information, and one of the lines "K2025, Dongjiang-Qingshibao" was particularly eye-catching. On the platform, a group of young people wearing brand new training uniforms and big red flowers on their chests were saying goodbye to their families. The air is filled with separation sorrow, exhortations, and an uncontrollable excitement mixed with confusion - this is the day when the new recruits set off.
