Definitions (粵典–words.hk)
  1. 語句、俚語
    粵​文化​傳統興​夏天​到​就​食​夏天​熟​嘅​荔枝​，​而沙蟬​（​蟬​喺​廣​東​話​入​面​個​舊​名​）​一叫​即​係​代表​夏天​到​，​係​時候​食​荔枝​。
    Literally "the cicadas sing, and the lychee is ripe". In Cantonese culture, there's the custom that one is supposed to eat lychee once summer comes, since lychee is at its finest in this season. The singing of cicadas heralds summer and thus, the harvest of lychee.
