Winter curtain festival, that is, the real winter to the day before and after. It is unique to festivals. If you miss it, you can only wait for next year.

When the festival comes, everyone will receive a letter and have a chance to have this painting in it, provided that you learn to cook. I'm not sure if there is a cooking requirement to receive it. Every number I learn to cook is full.

In addition, during the festival, LM is sold in the Tiebl of Og and near the bank.
