The mother and child care chain "sister-in-law" was established in august 1999. Currently, there is a national institution approved by the ministry of education as the focal point for the training of sis-in-law; a national institution for the certification of the training of older sis-in-law (mother-and-child nurse), sis-in-law (baby nurse) and lactator; and a national chain of institutions focusing more on the provision of early care services for infants aged 0-3 years. In 2001, "sister-in-law" had organized and patented specialists to develop various technologies; in 2002, she had also taken the lead in preparing a series of maternal and child-care books in china, and had prepared a programme for the specialized training of mother and child caregivers, nursery teachers and lactators at all levels, as well as an accreditation programme. This had filled the gap in the industry and changed the "classic" and "undocumented" dilemma in the country's mother-and-child care sector in that regard, making it the leading enterprise in industry standards. In order to make it easier for pregnant women to learn more about mother and child care and to know more about the personal records of nursing personnel, "sister-in-law of zi yu" invested at the end of 2002 in the establishment of china's larger maternal and child care industry portal, the monthly family home network of china and the expert advice hotline. The website now serves as the country's larger collection of breast-nurses for nannies (sister-in-law) and runs a 24-hour filing and referral system that allows employers to access the files of needed talent at any time. In 2003, in order to safeguard the interests of the clients, improve the efficiency of the work of the care providers and address the difficulties of client supervision of the work of the service providers, the "sister-in-law of the same month" invented the "sister-in-law's journal of work " . In 2008, the child caregiver's work log was launched, which significantly improved the level and quality of services in the infant care sector and improved monitoring mechanisms in the mother and child care service sector. Due to the special nature of the caregiver's home, the "sister-in-law" regularly conducts rigorous physical health checks for all staff members and provides temporary residence permits to staff members in the field to provide genuine access to scientific, professional, safe, healthy and reassuring care services. Thanks to the unique service philosophy of "sister-in-law" and the scientific approach to mother and child care, since its inception, the government has been receiving support and social attention from dozens of media outlets, including the people's daily, central television, china educational television, hubei watch, people's network, xinhua network, xinhua network, chu tian city news, among others, for many years; and in 2009 it was rated by the central television as "the pioneer of entrepreneurship". "sister-in-law" has been actively engaged in social responsibility for the public good and has been highly valued and appreciated by the government over the years. In 2008, "sister-in-law" made a significant contribution to the government's re-employment project, which was rated by the government as "the unit of excellence for re-employment"; 5. 12 wenchuan earthquake and 4. 14 jade tree earthquake, all members of "sister-in-law" actively contributed, and the media rated it as "a caring enterprise". Since 2006, with the assistance of the shanghai front chartered management adviser, "sister-in-law" has introduced a mature european business management concept, with a unified image of the chain, a unified service code and a unified training certification system. It is planned that there will be 100 national chains in the next three years, which will provide a solid foundation for the creation of mother and child care. In 2010, "sister-in-law of the same month" will remain committed to the "scientific sitting moon, happy life" service, providing 24-hour, 24-hour, personalized mother-child care services to many new mothers and babies in the month, and, in particular, providing follow-up services to the early association of 0-3-year-olds, intellectual development and life care, as well as more specialized star-child-care services for employers, and child-rearing services for high-end employers and foreigners.
