The so-called "360 lines" refers to all walks of life, that is, social posts. As the saying goes, "knock on gongs to sell sugar and do your own thing." There have been 36 lines of records about karma since the Tang Dynasty. Hui Zhou's Qingbo Magazine in the Song Dynasty recorded meat shops, seafood shops, sauce shops, flower shops, fresh fish shops, palace powder shops, ready-made clothes shops, medicinal materials shops, tie shops, coffin shops, secondhand shops, pottery shops, funeral shops, drum music shops, juggling shops, leather goods shops and so on.
