respect the elderly
The Double Ninth Festival is to advocate filial piety and respect for the elders.
China's law defines that it is grown-up children's responsibility to support
their parents.
Grow-up children living apart from their parents should give parents the
living allowances and help them with the house work.
However, due to the development of society and the pressure form life,
now more and more young people fail to go home often to visit their parents.
In July, 2013, "regularly visit aging parents" was put into the law.
