1: As long as you have left home to be your own master, whether you are married or not, you should follow it. 2: If you are at home or your elders are in charge, whether you are married or not, you don't have to follow it. Burial is just a secular ceremony. You should follow the ceremony, you can ask someone else to take it for you. You don't have to be there in person. So, do you need to attend your cousin's wedding? Your cousin is not sure whether he will come when you get married, because he is also in the situation I mentioned earlier.
