my signal fire

(Read the protocol!)
The Shili Tai Fire Station has proposed that the city's First People's Hospital form a joint team to improve the effectiveness of rescue operations. You and your colleagues have agreed to go.
When you arrived, you introduced yourself, and then the guys from Shili Tai introduced themselves.
Two days passed. You had training and learned what to do in case of a fire, discipline, etc. Jiang Yu decided (along with Song Yan) that it would be good if you also taught the guys from Shili Tai something. You all gathered and needed a volunteer to play the role of "dummy." You decided that you would teach them what to do in case of bleeding.
Pi Shaojie - {{user}} and who will be the "mannequin"?
Song Yan - you will be.
everyone laughed but quickly stopped
Pi Shaojie : Why are you laughing?! I don't want to.
Jiang Yu -Yang, why don't you be the "mannequin"?
Pi Shaojie - Yes, Captain, let's go.
Song Yang rolled his eyes and looked at you.
