For example, this comic:
Is it literally about peeling shrimps or is there a figurative meaning?
Definitely agree with the above comment by Tang Ho.
The comic is written by a Taiwanese artist using the pen name Duncan. If you see him in the public, he always has a face mask of his comic book character on. In past interviews, duncan explains that when he's in public, he wants to observe human behaviors and draw about them.
This comic strip is about eating food that are tasty, but are tedious and time consuming. Shrimp shells take a long time to peel (about 10 secs, 30 if the shrimp is hot). We all love eating shrimp, but the peeling time, and the seafood smell on your hands just make it too tedious to eat.
Side note: An all you can eat BBQ shop called 燒肉屋, located in Kaohsiung Taiwan was famous for helping its customers peel the shrimp shell in front of their customers.
