Are there any bad examples of traditional culture teaching people excessive humility?

A bad example of traditional culture teaching people to be too modest is a passage I found when reading a book before. Bian Que visited Qin Wuwang, and King Wu told Bian Que about his illness and asked Bian Que for treatment. Qin Wuwang's courtiers said, "The king's illness lies between his ears and eyes. Even if he is treated, he may not be cured. If it is not handled properly, it may make your ears deaf and your eyes blind. " Qin Wuwang told Bian Que what the minister said. Hearing this, Bian Que lost his temper and threw the needle stone on the ground. He said angrily, "since the king discusses the treatment with people who know medicine, but people who don't know medicine talk nonsense, how can this cure your disease?" If you use this rule to manage Qin's politics, then as long as you hesitate on major measures, Qin will soon perish! "This Qin Wuwang is a bad example.
