I think it originated from the concert of 9 1. This gesture is a gesture of love. Beyond love is different from love now. They sing love beyond themselves. This gesture was vividly displayed in "Days of Our Lives" and "Amani" at the 9 1 concert. Songs can not only entertain and listen to melodies, but also cultivate our hearts and make me more focused. Now, this gesture, like beyond's trademark, contains many meanings. As long as we hold this gesture high, it shows that we care about peace, care about children, oppose racial discrimination, love our parents, and don't hesitate!
