Weighing hard vegetables in an iron pot is a two-part allegorical saying. The pot is heavy, so it sinks to the bottom. Describe a person who is confused, unreasonable, regardless of laws and regulations, regardless of man-made accidents, and things are mostly ruined by him, ignoring anyone's persuasion and going his own way. Like a stone in the toilet, it stinks and is hard. Hard food is not listened to, and no one dares to provoke it.
