The music played in Tan Weiwei’s Run Brothers is called Yanyangtian Dai song. Fragment of lyrics: On a sunny day, on a sunny day, peach blossoms are like fire and willows are like smoke, and they are drawn between the beams early, pairs of pairs of flying swallows, the daughter is in tears, the daughter is in tears. Today is the eighteenth year of my life. The sky is full of spring. Who is accompanying me? Who is accompanying me? The sunny sky, the bright sun, the lakes and mountains are reflected on the curtains, spring is full of the Old Summer Palace, the two cranes are sleeping with their necks crossed, the daughter is in tears, the daughter is in tears ripple.
