Expressing “Needless to say” with “gèng bùbì shuō”
更不必说
How it works
更不必说 (gèng bùbì shuō) means “needless to say,” “let alone,” or “not to mention.” It is used when the first case is already clear enough, so a stronger or more obvious case does not even need to be mentioned.
It often appears in reasoning and comparison.
Example sentences

Key point
This expression strengthens comparison by moving from a strong case to an even stronger one.
