today I learned a new word: cockroach–a dirty animal, but how I should I remember it, so I made a memory hook ：“烤个肉吃” that is the encoding element I created. when I speak the  voice of cockroach, an image of Bear Grylls eating the wild meat came into my mind, it is very exciting and disgusting, the strong impression helps me keep the word in my mind

however, I never  want to see the cockroach
