Chuseok is also known for Charye (차례), which is an ancestral memorial service that is thousands of years old. Traditionally, families gather together, hold a memorial service for their ancestors and offer food (such as Songpyeong) to the deceased. These formal Charye events only happen on Chuseok and on Seollal, which is New Years Day.
These formal costumes are some examples of what people would wear to Charye.
