Why do Hakkas calculate their age by imaginary age?

It is said that this imaginary age algorithm was handed down by their own ancestors.

At first. I think it's because Hakkas have their own special calendars, or some of their own knowledge to calculate.

Later, I saw some information saying. Hakkas are descendants of the old clan in the Central Plains, and later moved to the south of the Central Plains at that time. They began to use fictional age to express their age. At that time, they didn't have the concept of one year old at all, and this method has a long history from their ancestors and has been used until now.

In our daily life, we all use heavenly stems and earthly branches to calculate our own age, or other people's age, and it is calculated according to the age corresponding to the twelve genera, with twelve years as a round.

So in our life, it is possible that you ask others how old they are, and others will answer you that I am a round older than you or a round younger than you. So this sentence means twelve years older than you or twelve years younger than you.

Moreover, the ancestors of Hakka people have long known the phenomenon of 2008. They regard "Nian" and "Nian" as concrete objects, and regard "Nian" as an additional age.

According to the Hakkas, a person is one year old when he is born, which is called nominal age, and then he will grow old according to his age.

Actually, in our family, that is to say, we are not one year old. If it is the twelfth birthday, in fact, most children are thirteen years old in vain.

The customs and cultures of each place are different, and Hakka people have their own algorithms for age.
