What gestures should students use to release vending machines faster to win prizes?

You can show your award-winning trophy or certificate when shooting a self-driving car faster, and give a thumbs up next to it.

Most thumbs-up shows appreciation for a sentence or something. This is the most commonly used gesture in China, which expresses praise and approval, and also expresses gratitude for others' actions, thanking others for everything they have done for you, and indicating that they are ready.
