Standing not confused, weak-crowned cardamom, all describe a person's age stage. There is no doubt that the age refers to forty years old, which means that you can distinguish clearly when you encounter difficulties. Because it originated from Confucius' saying, "Be determined to learn five out of ten, stand at thirty, not be confused at forty, know the destiny at fifty, listen at sixty, and act at seventy, without overstepping the bounds." Therefore, people aged 40 to 40 are called "the year of no doubt" by later generations.
There is a folk saying that "in the year of no doubt, three things will not change, and in the year of know life, three things will not touch". The so-called "three invariants" means the same work, the same feelings and the same health. Generally speaking, when people reach middle age and 40 years old, their minds are mature enough to stop being confused about the world. At this stage, the ability to work will decline, and it is not suitable for changing jobs and emotions. At this stage, we should pay attention to exercise, keep healthy and pay attention to health preservation.
In ancient times, in addition to "not confused" to describe people around 40 years old, babies under one year old were also described as "swaddling clothes", and the total angle was the general term for childhood; Cardamom refers to a woman who is thirteen or fourteen years old. There are also twenty-year-old men called "weak crowns" and women over fifteen called "women".
