Be careful to verify quotations to avoid attributing them to the wrong person.
Tips
history
Recorded in Ming scholar Tian Yiheng's 《留青日札》, citing a folk saying: 'Zhang's hat ends up on Li's head.' Zhang and Li are the two most common Chinese surnames — equivalent to swapping 'Smith's hat' for 'Jones's' in English.
usage
Classic for misattribution: quotes, authorship, credit for ideas, faces to names. Milder than 颠倒黑白 (invert black and white), which implies deliberate distortion.
