Why to eat tofu when you get out of jail?
In Korea, when someone is released from prison, the person is fed with a tubu (tofu). In her book Dubi, Korean novelist Park Wan-seo explanation of this custom is:

 "A life behind the bars is said to be "eating boiled beans." A tofu has been released from beans but can never return to beans. Thus a feeding a tofu might mean a wish that the person would never go back to prison."
