During one training session, after running 10 laps around the track, Tang collapsed from exhaustion. His fellow recruits lifted him up by the arms, carrying him across the finish line. "That was when I understood: no matter how hard it is, a soldier never gives up," he said. "We are one team."

During Chinese New Year's Eve in 2020, while families across China gathered in celebration, Tang stood guard. When midnight struck, fireworks lit up the sky, and the air was filled with the sounds of joy and celebration. "It was the first time I truly felt like a soldier," he said. "Thanks to thousands of soldiers on duty, civilians can celebrate each Spring Festival in peace."

His band would later capture that sentiment in a song: "Whose watchful eyes guard the countless lights of home? The finest of military devotion is given to the motherland."

Tang was later assigned to the Red Outpost Company, a unit with a distinguished legacy.

Chen Dahai, a former adviser to the unit, recalled: "We moved camp three times to accommodate the construction of the Hong Kong-Zhuhai-Macao Bridge. Though the living conditions were tough, we never failed in our duties."

Beyond their missions, soldiers from the unit also regularly visit and spend time with children with disabilities.

Tang believes music is a powerful way to pass down the unit's spirit. "Music can enlighten and heal," he said.
