The countryside has also begun to have "fast-food marriages". Why is marriage so unreliable now? A fast-food marriage is a marriage that is completed in a short period of time, usually only a few months or years, rather than a long-term marriage commitment. This kind of marriage was usually built on a weak emotional foundation and a lack of mutual understanding. A fast-food marriage is easily disturbed by external factors such as work pressure, family conflicts, and relationships with friends. These factors may lead to the breakdown of the marriage. In addition, due to the short duration of the marriage, both parties may not have enough time to establish a deep emotional foundation and it is difficult to maintain the stability of the marriage. The fast-paced life in modern society may also cause people to not have enough time and energy to seriously consider marriage. Many people may only focus on immediate benefits and ignore long-term marital stability and happiness. To sum up, fast-food marriages and the rapid development and changes of modern society may lead to the instability of marriage. Therefore, to establish a long-term, stable and happy marriage requires both parties to work together to establish a deep emotional foundation and consider various possibilities in the future.
