(idiom) to insult indirectly or criticize someone obliquely; literally "to point at a monk while cursing a bald man"

A two-part allegorical saying (xiehouyu) meaning "defying both human and divine laws". It relies on a pun where "hair" [[发|髮|fa4]] sounds like "law" [[法|法|fa3]], and the umbrella hides the "sky" (symbolizing heaven or divine justice). Since a bald man has no hair and his umbrella blocks the sky, he is [[无法无天|無法無天|wu2 fa3 wu2 tian1]].
