Yue Yue is the common name of maternal and child care practitioners. It is a professional nurse for mothers and newborns. The traditional service period is generally one month after the newborn is born (traditional confinement is 30 days). Yue Yue is a professional, different from ordinary domestic nurses, and must be certified. Under normal circumstances, Yue Yue's main responsibilities include neonatal care, maternal care, maternal and child supplies and the sanitation of relevant areas. Usually, the service time of Lunar New Year is divided into 4 hours and 24 hours, and the vast majority of Lunar New Year services are provided at users' homes.

The person in charge of the Vocational Skills Appraisal Administration of a provincial labor and social security department said that the labor and social security department has never specifically recognized the vocational qualifications of Yue Yue and Greater Yue Yue, but classified them as domestic servants. Therefore, from the perspective of professional qualifications, there are no two kinds of statements: certification month and advanced month. (except Shanghai)

The person in charge reminded that the professional qualifications of the national labor department are divided into five grades, namely junior workers, intermediate workers, senior workers, technicians and senior technicians. The self-styled "grades" of some units are not authoritative and credible, so consumers should pay attention to identification.

According to the documents of the National Certification Center, at present, only three levels (baby nurses), four levels (senior baby nurses) and five levels (baby nurses) have been awarded.
