How do primary school students recite the action of "flute in the night city"

Cross your hands on your chest, bow your head slightly, then slowly raise your head and open your arms.

Or cover your heart with one hand, then slowly open it in half, with your arms bent in half, and your palms naturally inward or upward.

Then the palm slightly swings up and down in a small wave.

Stretch forward slightly, then put it back on your chest and bow your head slightly.
