求翻译：11、牵新:娘新娘由礼车走出时，应由男方一位有福气之长辈持竹筛顶在新娘头上，并扶新娘进入大厅。进门时，新人绝不可踩门槛，而应横跨过去。是什么意思？

11, led the new: Mother car out from the ceremony when the bride should be a lucky man who's elders, the bride's head at the top of the bamboo screen and help the bride into the hall. Door, the couple must not step on the threshold, but should be across the past.
