Excuse me, what happened to Liu Qian's rubber band magic performance in the Spring Festival Evening of 2009?

As soon as the hand turns, change hands and point to the hand that is doing the action. First, the middle finger and thumb are wrapped in leather.

First, the middle finger is up and the thumb is down. When moving, the middle finger is down, the thumb is up and the hand is pulled back. At this time, the index finger is inserted next to the thumb, the middle finger is released, and the hand is turned around. Just try it.
