Since 1950, the rapid increasing population resulted in a high density of survival space; population pressure became a heavy burden between the economic development and the health care; some of the rural and remote areas were still facing all obstacles in family planning. “I” had my baby, and what was the possible business with you? Was there any consciousness of “others” in the issue of the population? Restaurants made huge profits through the purchasement, killing and cooking of wild animals. Meanwhile eaters didn’t bat their eyes when they were enjoying or just for showing off wealth. Officials didn’t hesitate in making rare wild animals as the highest banquet. Paving one’s way of promotion through bribing, was there a position of “others” in this destruction of the “human chain” of the natural ecology? For a long time, the public health system in urban and rural area was never ever paid attention to: the dirty, noisy and disorder of offices, daily disinfection protection in public, hand-washing equipment in public convenience, sewage treatment, house refuse and so on. However, there was a surprising consensus of mentality between managers of public health and managed: this was not my personal business. Is there any concept of “others” in these ignored and forgotten places of public health? So many bad habits were accumulated in hygienic customs in people’s daily life: spitting, nuisance, littering, and difficulty in carrying out separate eating, drunk driving, and smoking in public places and so on…the traditional culture of “we” was “not afraid of scarcity but inequalities”- in the habitual behaviors of equally sharing interest and misfortune, weal and woe, was there a sense of responsibility of self-discipline and self-control so that “others” may avoid the disasters?
It seems that we are constantly and unconsciously paving ways for it arrival. However, “zero distance” is harmful in public areas. Distance is “others” while “others” means social ethics, for on this planet there are more unfamiliar “he”-“others”, and “it”-the animals coexist with human beings except you and me. It is for the safety and freedom of “I”, no more self-center please but more love and care about “others”. The freedom of “I” is the end of freedom of others. At the same time, only the freedom of others can finally achieve the ultimate freedom of "I".
