One sweltering summer's day Dr Panda and Sha Daiai are chatting in the restaurant when suddenly someone comes in asking for help. He has excruciating pain in his lower right abdomen and suffers from fever, nausea and vomiting.

Dr Panda examines the man and determines that he has appendicitis. Sha Daidai then starts asking questions such as what appendicitis is, the cause, the symptoms, methods of diagnosis, treatment and the prognosis.

In the end Sha Daidai takes off his clothes to reveal a small scar, a remnant of an appendectomy－which to you, me and Dr Panda is an operation to have the appendix removed.

In the cartoon panels Sha Daidai is depicted asking each of his questions as he contorts his body into outlandish positions and wears different facial expressions. Dr Panda answers in plain, concise language that is accompanied with easy-to-understand illustrations elucidating what he says.

As with other stories, many readers use the comments section to talk of their experience with similar ailments and express their thanks for what the cartoons have taught them.
