There is no rule about whether to hold a banquet when you get married. It depends on whether the two sides agree or not, and the economic conditions in your area. If conditions permit, it is also good to invite friends and relatives to get together and celebrate. Generally, weddings and banquets are handed down from local folk customs. There are many choices for traveling weddings or group weddings now. After all, the times are developing, and it is certainly understandable not to hold a banquet. As long as you are happy, I wish you a happy wedding. . .
