This light national style comedy soundtrack takes 6/8 waltz as its skeleton and skillfully combines piano, double cello, pipa, erhu and other folk music. Through staccato, slide and allegro, mandarin duck board and other crisp percussion, create a very viral sense of humor and plot tension. The music presents an absurd atmosphere of creeping and clumsy stealth. The misplaced collocation of Chinese and Western musical instruments is highly recognizable, which is very suitable for funny reversal, variety show, adoration and short video plot scenes of market life.
