The reason why there is no gap between engagement and marriage can be explained mainly from two aspects: cultural traditions and practical considerations.
First of all, from a cultural and traditional point of view, engagement and marriage are seen as important milestones in life, important moments in building a family and passing on the line. In traditional Chinese culture, marriage is a major life event that needs to be treated with caution. Therefore, the time gap between engagement and marriage is seen as a respectful and discreet attitude that allows both parties to get to know each other better and lay a solid foundation for future married life. If you remarry the next year, it may be seen as not taking the marriage seriously enough or being unlucky.
Secondly, from a practical point of view, there are also many benefits to not having alternate years between engagement and marriage. For example, planning a wedding immediately after the engagement can make better use of both parties' time and resources, making it less difficult and costly to prepare for the wedding. In addition, not having a split year between engagement and marriage also helps to keep the relationship fresh and hot, reducing anxiety and dissatisfaction caused by long waits.
Of course, in some cases, it is understandable that there will be alternate years between engagement and marriage. For example, in some regions or cultures, the time gap between engagement and marriage may be seen as a way of respecting elders or traditional customs. Also, for some young people, it may be necessary to wait for a while after getting engaged before they can get married due to work or other reasons.
In general, the reasons why there is no gap between engagement and marriage are mainly cultural traditions and practical considerations. While respecting tradition, we should also make reasonable choices according to the actual situation to lay a solid foundation for future married life.
