This is originally a folk tune based on which Nie Er had adapted into an orchestral piece in 1934. It was transcribed into a duet version before the Chinese New Year in 2019 and was immediately performed and recorded by HKDuo (Hui Ling and Julie Kuok) as a one-minute video clip to be posted on the HKDuo Facebook page. It went miraculously viral and many people around the world asked for the score! The alternating hand clapping effect between the two players adds extra joy fun and joy to the jubilant music.
