You can't buy shoes in the first month, which is a folk culture in some places. Mainly because the word "shoes" is homophonic with the word "evil", not buying shoes is a beautiful expression of hope to avoid evil and make money.
If you can't buy shoes in the first month, you have to remind people to get new shoes ready in the twelfth month. In addition, throwing a pair of old shoes on the first day is a good thing, representing evil spirits, which is a good sign.
