In the movie "Tong Pak Hu Dian Qiu Xiang", Tang Bohu pretends to be ill, and the doctor says "your legend". What does this mean?

"Your Legend" is an ancient musical name, which is usually used to describe the orders of military commanders. In the movie "Chou-heung in the Temple of Tang Bohu", Tang Bohu pretended to be ill, and the physician heard that Tang Bohu's heartbeat was different in the process of taking the pulse, but he was not sure what the problem was, so he mentioned "Your Legend", suggesting that Tang Bohu's heartbeat rhythm was similar to that of a military commander, indicating that Tang Bohu's heart problem was more serious.
