Tips
memory
An ABAC pattern: 杂 (zá, 'mixed') is reduplicated, and 七 (seven) and 八 (eight) play the same role as English 'six and seven' / 'all sorts'. The numbers don't mean anything literal — they just signal jumbled multiplicity.
register
Colloquial. Compare formal 五花八门 'all kinds' (more neutral / variety) and 乱七八糟 (luànqībāzāo) 'a complete mess' (more negative).
