Early education teachers are workers engaged in professional education for infants aged 0-6. Early education involves a wide range, such as infant physiology, psychology, brain science, and even female psychology, thinking science and other disciplines. Therefore, the professionalism of early education teachers is still quite strong. With the liberalization of the three-child policy and the strong support of the state for the birth of three children, domestic early education institutions have sprung up like mushrooms after rain. According to statistics, there is an increasing demand for all kinds of teachers in large and medium-sized cities in China. Up to now, the gap in early education industry is as high as 2.5 million. Compared with the huge demand, the early education and child-rearing industry in China is still in its infancy.
