In the long course of marriage, the relationship between husband and wife is complex and delicate. Sometimes, we need to snuggle up to each other and face the ups and downs of life together; Sometimes, you need to keep an appropriate distance to give each other a little space and privacy. The so-called "distance of zhang" is not a unit of length in the actual sense, but refers to an appropriate distance between the wife and her husband in mind and emotion.
Keeping a "distance" is a sign of mutual respect between a wife and a husband in a marriage. Respecting each other's independence of personality and individual needs means acknowledging that the other's existence is not just an accessory to one's own life, but a person with independent thoughts and emotions. Wives should not be overly dependent on their husbands, and husbands should not be overly controlling their wives. Rather, they should be like two separate trees, close to each other but not entangled with each other, supporting a shade of greenery.
The "distance" is a buffer zone for emotional communication in marriage. There will inevitably be friction and misunderstandings in married life, and keeping a certain distance can avoid the accumulation and outburst of these negative emotions. When wives and husbands each have a certain amount of personal space, they can think more calmly and deal with conflicts more rationally. This distance is not an alienation, but a healthier way of communicating emotionally. 
In addition,"The distance of the zhang" is also a necessary condition for personal growth in marriage. Everyone is a unique individual with their own dreams and pursuits. Keeping a certain distance can give both wives and husbands the opportunity to pursue their own interests and hobbies and realize their own values. Such a marriage is not only a partnership that supports each other, but also a partnership that grows together.
Of course, emphasizing the "distance of zhang" does not mean completely ignoring each other's existence, or a passive avoidance of marriage. Rather, it is a positive strategy in married life to better maintain the health and stability of the marriage. Wives and husbands should maintain close communication and contact while maintaining a certain distance, so as to create a warm and harmonious family atmosphere together.
The "distance" is not an insurmountable chasm, but an invisible boundary that establishes a dynamic balance between the wife and the husband. This balance not only guarantees the independence and autonomy of both parties, but also maintains the integrity and stability of the marriage.
Over the course of marriage, wives and husbands need to constantly adjust their positions and postures to adapt to each other's changes and needs. Only in this way can they go through every stage of life together and create happiness and beauty that belong to them together.
