In China, why do young people "have to" buy houses and get married? And why do they impulsively get divorced? This is determined by the household registration system and is also a measure of social dignity. It is not simply a matter of will, but a strong binding of social contracts. In many cities, a house is not just a living space; it is the "entry fee" for settling down, social insurance, and especially for future children to receive quality education. Not buying a house means being on the margins of the distribution of urban public resources. The most contradictory part is:

To get married, taking on huge mortgage debts often becomes the last straw that destroys the marriage. High debts reduce the margin for error in life to a very low level. Both partners dare not take a break at work and dare not spend in life, and this extremely tense state can turn any small spark (such as who washes the dishes, who takes care of the children) into an explosion of "must divorce" in an instant. Logically speaking, this is actually a dislocation: we use the most traditional material standard (houses) to forcibly wrap the most modern emotional relationships (extreme individualism).

Modern young people (especially highly educated women) are more independent economically and spiritually. When the marginal benefits brought by marriage (emotional value, convenience of life) are lower than the marginal costs (household chores, conflicts with in-laws, loss of freedom), withdrawing investment becomes the most direct way to cut losses. People in the past married for "survival"; as long as they could get by, they could endure it; but now people marry for "happiness." When real life (trivial, mundane, quarrels) cannot match the high expectations before marriage, the psychological gap quickly turns into anger.
