The following:

1, 13 to 15 years old teenagers are called the year of the dance spoon.

2. Boys 15 years of age are called the year of Chihuahua.

3. Girls aged 12 are called the year of the golden hairpin.

4. The age of 13 for girls is called the year of cardamom.

5. At the age of 15, a girl is said to be at the age of maturity.

6. A girl at the age of 16 is said to be in the year of jasper or broken melon.

From the provisions of the Book of Rites, 10 years or less is the equivalent of the modern juvenile stage; 20 years old is the demarcation line between immaturity and adulthood. 20 years old or less is immaturity, which is 2 years higher than the current age of 18 years old or less. At the age of 20, a person became an adult and had to perform the "crown rite". Crowning is a unique rite of passage in ancient China, also known as the "rite of passage", which was quite grand in the early days, with the participation of family members, relatives and friends, and village elders.

There are also references to classical literature that denote children of different ages. For example, at the age of 13, it is called "dancing spoons", which is derived from the saying in "Li Ji - Nei Zi" that "in the third year of the tenth year, one learns music, recites poems, and dances spoons"; and at the age of 15, it is called "becoming a child" or "the year of dancing elephants". The term "15 years old", or "the year of the dance of the elephant", is based on the statement in the Book of Rites - Nei Zuo (礼记-内则), which states that "a child becomes a child, dances with an elephant, and learns to shoot and defend".
