Playing the trumpet is very particular: when you arrive in the afternoon on the first day of the wedding, you can play all the way when you invite the Lord. Is it lively or not to blow for a few hours at night? When you pick up the bride in the morning, you must blow it on every bridge, intersection, river ditch, village and other places. And you must keep blowing at noon, and you can stop at the end of dessert, which is basically over. Different places, different customs, I hope it will be useful.
