on the day of their ancestors' death, on Korean new year, and on Chuseok (Korean: 추석, Autumn eve). The unity of the family community is strengthened because all families must gather together to prepare and hold events together during Jesa. One food-related custom is gimjang. Many Koreans make a large amount of kimchi when the temperature drops in late fall. In spring, each household ferments seafood such as shrimp and anchovies with salt. In summer, they buy a thousand-day salt which is used to store the foodstuff for two to three years until its bitter taste is gone. In late summer, red peppers are dried and grinded into powder. In late fall, housewives decide the right date for kimchi in part through consideration of the weather. Innovative techniques and creative ideas are shared and accumulated through the custom of sharing kimchi at home after making kimchi. This custom helped foster community ties, as family members and village members gathered together to make kimchi. Folk arts Korean folk arts have often been passed down within Korean society. Korean folk art is characterized by many works satirizing the upper class and high society. Minhwa Minhwa, or folk paintings, is a popular painting genre, noted for lacking consistent perspective and being fluid in their style. They are contrasted with the styles of paintings created by professional painters. Painting related to the public's desire to chase away bad ghosts and face a happy occasion, paintings to decorate the inside and outside of the house, and paintings directly related to everyday life such as folding screens, scrolls, and murals made up the mainstream of folk paintings. Minhwa was used to decorate the living and ceremonial spaces of the private sector during the Joseon Dynasty. After securing marketability through economic growth after the late Joseon Dynasty, it was distributed through the market in the early 20th century. Since Minhwa originated from imitating paintings of court and other high-class demand, most of the plants were similarly painted on the subject. Traditional Korean paintings depict stories or events of historical and cultural significance, conveying popular metaphors and symbols.

Minhwa have also been known to cover these topics, with subjects ranging from themes that repel evil to sentimental topics such as landscape painting, characterization, and botanical painting, as well as old stories and myths.
