Create a short, emotionally resonant video with a cinematic feel, depicting a middle-aged Chinese businessman running through a torrential downpour to catch his high-speed train at the last minute. Exhausted and overwhelmed, he relaxes in his seat, only to be horrified to discover his train door is ajar when he checks his phone. The camera focuses on his rapidly changing facial expressions, from relief to shock, regret, and finally, deep frustration.
