Yes In some places, my uncle, as one of the elders of the newlyweds, has the custom of pressing the manhole cover for the newlyweds. This custom is also called "lucky money", which means to give a sum of money or a gift to the newlyweds to wish them happiness and early birth. These customs all hope that the newlyweds can successfully overcome all kinds of challenges in their marriage life, be happy and have a harmonious family.
