Since ancient times, it was said that officials gave up their lives to maintain justice, and soldiers fought with their lives for victory. However, there were very few people with such boldness.
That old minister's surname was Gu, and he was not famous in the Imperial Court. He had wasted half his life and was already close to the age of compulsory retirement.
The Imperial Court had a clear rule that once an official reached 70 years old, they had to retire on their own. In addition, although one was still young, it was still acceptable to describe them as old.
Therefore, most officials would resign before they reached 70 or even 60.
The Imperial Court also needed new blood to continue operating.
