A two-part allegorical saying (xiehouyu) meaning "defying both human and divine laws". It relies on a pun where "hair" 发 fà sounds like "law" 法 fǎ, 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 wú​fǎ​wú​tiān.
