You need to make an appointment in advance to go to the leader's home for the New Year.

If you want to pay a New Year call to the leader, you can make an appointment like this. You can tell the leader that you want to pay a New Year call to such a leader, and then you need to ask the leader when he will be free a few days ago, and then you can go to a restaurant for dinner or go for a walk when you are free.

It will be politely refused, but in the end, it is still welcome. You said it was new year and wanted to see you. Do you think you are free/at home around XX in the evening? He'll talk.

If he says no, you should ask at once, is there anyone at home, is my sister-in-law at home, and when will you be free? Be sure to hurry.

In short, a phone call will definitely finalize the time!
