Su Tang saw that there were still some confused looks on everyone's faces, so she thought for a moment and plucked a blade of grass from the ground.
"Look at this blade of grass, what comes to your mind? Fear not to make bold guesses, let your thoughts flow, and just say what different words or phrases it reminds you of."
"Green."
"Sharp."
"Thin."
"Fragile."
"Plenty."
Su Tang nods in satisfaction.
"Exactly, the guesser needs to determine, based on the describer's actions and expressions, what they might be trying to convey. It doesn't matter if you get it wrong, there's no punishment, as long as we say the correct answer within the stipulated time."
"Okay, so what does the describer's affirmation and negation mean?"
"The describer can't speak, but he can use nods, head shaking, and various reactions to subtly guide the guesser towards the right answer."
