Food is important part of every culture.

Food and cooking in every culture demonstrate the way of life
in the aspects of knoweldge, behavior, and social preferrence for particular group of people. 
Kimchi is an integral part of Korean living becuase it is a fixture in every Korean meal:
It is served three times a day, 365 days a year as long as the meal is Korean.

Becuase of its permanence in nature, Kimchi is never gone from Korean households. 
Empty Kimchi jar meant that some disaterous event has occured in that family. 
So what do Koreans do in order to keep Kimchi Jar full at all times?
They not only made Kimchi frequently, ususally as a community,
but they would have also devised  ways to prolong the life of Kimchi while preserving the freshness and taste.

Kimchi is UNESCO Intangible Cultural Heritage of Humanity.

Kimchi and corporate Kimchi-making is recognized by UNESCO as Intangible Cultural Heritage of Humanity. The decision by the UNESCO committee to inscribe Kimchi as Intangible Cultural Heritage is articulated as following:
"Kimjang (corporate Kimchi-making) allows Koreans to practice the spirit of sharing among neighbors, while promoting solidarity and providing them a sense of identity and belonging. Inscription of Kimjang could contribute to the visibility of intangible cultural heritage by enhancing dialogue among different communities nationally and internationally that practice foodways that similarly make creative use of natural resources."
