As Hong Kong mourns a firefighter who lost his life battling a devastating residential fire, the city's music community is turning grief into support. A charity concert, "Salute to the Brave, Soothing the Soul," will be held on December 22 – three days after the firefighter's official funeral of the highest honors. All proceeds will go to his family. But beyond fundraising, the concert also seeks to uplift the spirit of the entire city. CGTN's Huang Fei visited one of the rehearsals.
