According to Confucianism, the society will function well if everyone knows their assigned place and does not question it.
In a Confucian society, people are not equal, instead, there is a hierarchy:
<span>ruler >subject,
father > son, (we can assume that they mean parents> children)
husband > wife,
elder > younger,
friend = friend - here people are equal with respect to each other.
</span>
So we see that filial piety is a way of ensuring that this relationship: father > son functions without a problem, and the Confucians believed that this is necessary for the proper function of the society. <span />

Boats of the modern era have evolved a lot. From sailing boats, to large rowing boats like the Viking longships, to mechanical boats of the modern era. This evolution is to be expected since boats are among the first human inventions in history, dating back to thousands of years before the Neolithic Revolution.
