One radish, one hole. (Each person has their place.)
Tips
usage
萝卜 by itself usually means white radish (daikon). 胡萝卜 is carrot, and 红萝卜 can mean either carrot or red radish depending on the region.
mistakes
The second character 卜 is pronounced 'bo' (neutral tone) here, not 'bǔ' as in 占卜 (divination). This is a classic example of a character changing pronunciation in a compound word.
