Abstract: As for maintaining and ensuring human dignity, a reasonable partition is important, and is a basic legal measure as well. The reasonable partition embodies a environmental need for a mechanism of realizing dignity, maintains the rule of courtesy in keeping average distance, and establishes a private domain of individual exercise. As for the laws, it is necessary to admit the human liberty to be in solitude separating from the others, to protect the privacy of the subject from the others’ knowing, to designate a private space separating from the others’ peeping, and to prohibit offensive contact in social occasion. As for the legal limits and regulations of reasonable partition, it is to unify private exercise and civil responsibility, to define the rules of offense by general sense of the whole society, and, at the same time, to eliminate the ways of racial segregation, social repelling and forcing the others to disappear or to separate from the outside world by illegal means, in order to realize a genuine human dignity.
