Life is like a river, in which each of us rises and falls, choosing what we think is the most correct, but fate is absolutely different, but we still have to live proudly. Gear Yarn Lu tells different stories about the relationship between genius and society. The four actors in the play play play four corners, but they play the role of genius together. They change roles like gears, and they talk like yarns. Where is the way of genius? This play makes you think about it.
