From the Song Dynasty of China began a family planning

   
The world's first claim to control population growth is the late Warring States and Han Fei politicians. In his "five beetle" in the said article: "... ... In ancient times, the husband is not cultivated, vegetation of the chronological food also, women do not weave, an animal skin full of clothes too. Things full force and keep the people more than less in the Finance So people do not fight. by Houshang not, heavy fines and instead self-government. people today is not more than five children, there are five sub-sub, Tai Fu Acquainted while 25 Sun. are people people and goods, which few, a matter of labor and support forces thin, so a competition. Baisho tired though not free from arbitrary punishment. "Han Fei to ancient demographic distribution of natural wealth for labor and social security income, etc. 11 contrast, profoundly demonstrated"few people will fight over money" argument. He do not pay attention birth control of population growth as a wealthy and strong country against a "five beetle", one is indeed food for thought!

Historically, the population of Han Fei's view than the eighteenth century to early 2000 the British Malthusian. China's Ming Dynasty in the 1604 scientists Guangqi "Lu Song disposal rates to check the proposed side", the proposed doubling of population every three years the law. Later, in "NongzhengQuanshu" (1633), he once again made this rule: "three years and probably doubled," "husband three years as I, I, each of the two men among the people." The Malthus in 1798, "Population Theory" proposed "doubling population every 20 years." Facts have proved that the law in revealing the accuracy of population growth, Malthus Xu Guangqi sooner than 194 years.
    Rural Southern Song Dynasty, there was a strange custom called "Son do not move," that gave birth to a child does not care, or throw away the baby drowned. Initially, this custom is also some superstitious, said fifth month the son ominous, ominous, so "do not give children", the "child" refers to the boy. But then this "child" actually turns out to include boys and girls, including all newborn babies, and not just referring to the fifth month. The "Son do not move" to the phenomenon of duration, the regions covered surprising. In Fujian, the Outward, Jinghu, south, etc. are widely distributed, especially to statehood, a fine state, Tingzhou, South sword state, Shaowu Jun, building Huining Prefecture, Ya state, and Yanzhou, Ezhou, Yuezhou, the letter states, Raozhou and so the most serious. Greatly influenced the proliferation of the population at that time, affected the development of rural economy, and because a large number of infanticide, abandoned children, causing serious imbalance between men and women, causing no woman can marry, trafficking in women, early marriage and other women continues to rise. It is worth mentioning that this "does not give birth to children" phenomenon, entirely spontaneous behavior of farmers, without any government restrictions.

In fact, the Southern Song Dynasty government is to strongly encourage fertility, and to take a lot of incentives, non-twins did not give the wind: Shaoxing eight Zong provides poor person pregnancy, support for m 4 fight. 15 years and to branch to a stone. Two years of relief to compensate for lack of Changping, founder of "Candidates positions" to help poor house novices who are unable to old-age support. The purpose of the Southern Song Dynasty government to do so there are two: First, the development of population, to improve productivity, increase revenue, to solve manpower, thereby enhancing national strength, to fight against the Jurchen, Mongolian Chinese and the country south. External and internal power to keep. Second, the Southern Song Dynasty Confucianism, Buddhism and Taoism together to the "Science" has formed a system dominated people's thinking, especially the Buddhist "Five Precepts" and the Confucian "five permanent members" used the "no kill" on the first position, contrary to the principle of "Son do not move" not only "no way", but not conducive to benefit the people running the country. However, for various reasons, reward and punishment measures are not implemented, "Son do not move" off the wind did not exterminate. One of the reasons of which is "to have more and more education" of self-revenge. "Many sons" is a feudal society with a deeply rooted concept of women's infertility and abortion is considered an ominous move, therefore, neither approach in infertility not have the means are not born, only to take " born reprocessing "the worst. At that time, the situation in rural areas, many women's reproductive birth in 8,9, or 10 more children. These women are often pregnant every year, every year production, but only gave birth to a child they could not afford the drowned or abandoned. The second reason is difficult for poor farmers in misery. Private ownership of land and further development of the Southern Song Dynasty. Land acquisition is very serious, a lot of land is increasingly concentrated in a few official households, rich hand, many small farmers become servants, more difficult to raise children. If Yuhan waterlogging injury or theft intrusion, farmers are even more difficult to meter. "Body Ding money" collection also contributed to have children do not move. Song is established, the provisions of 20 men, Cheng Ding, 60 for the old age people per household is satisfied by the small output of rice and silk money, collectively, the "body small money." Poor peasants overwhelmed, often taken to conceal the small population means to avoid "body Ding money" collection, affecting male population growth. Ineffective government relief measures. Local officials from corruption, to have children do not move long-standing phenomenon. Although the level of relief such as government policies often, but often flat owed serious case of famine and food rescue year is immune, not to mention ordinary people on the pregnancy of relief: the result of this policy, but a dead letter only. The third reason is the inheritance of property constraints to rural areas also have children in the affluent do not move. These people will be brothers, the more possessions the more fragmented, and this the more readily accessible by the merger, therefore, in order to keep family property, to consist in the drop off will not only have children do not move. More than the above, the rural Southern Song Dynasty, "Son do not move," the practice of the most brutal in the most savage primitive approach to control population growth, the economic, ideological, ethical aspects have a considerable negative effects, is also the future generations of people should ponder the lessons of history and warning.
