Why Chinese love ring? The small one is how to use contraceptive spermicidal? Sohu in the thirty-seventh period "mother kangaroo cartoon" parenting, kangaroo hemp to introduce the principle of the pill. We say the folk saying: "contraception: foreigners love medicine, Chinese love ring". In the United States, the contraceptive use rate of 80%, while in China, most people think it is very troublesome to eat contraceptives, and fear of what the impact on the body. So today, to introduce the widely adopted Chinese contraceptive measures: Kangaroo hemp ring. We actually called Sheung Wan, intrauterine device, a contraceptive device placed in the uterine cavity, due to the early use of multi ring, so we often call the contraceptive ring or ring.
