The early education industry was first introduced to China in 1990s, but at that time, Chinese people generally had no concept of early education. With the reform and opening up, China's economic strength has been greatly improved, and the post-80s and post-90s generation with higher education level has entered the reproductive age stage. Parents of the post-80s and post-90s generation tend to think that early education at the age of 0-3 is very important for the development of children's intelligence, personality and potential, so the early education industry in China has also entered a period of rapid development in recent years.

Due to the improvement of people's living standards in China, parents pay more attention to their children's early education, so various brands of early education came into being.

Red, yellow and blue is also one of the most famous brands in China. As one of the earliest local early education brands, it has always been a holy place for early education in the hearts of many parents with the advantages of being close to the people and grounded. Red, yellow and blue has now grown into a large-scale comprehensive early education enterprise, covering a wide range, and the number of shops and teaching staff can also be called a giant enterprise. Although the hardware facilities of red, yellow and blue are more localized, its courses are rich and fully meet the daily needs of children. However, it is precisely because of its extensive age coverage that early education has become standardized and curriculum-oriented. The education of red, yellow and blue at different ages is unclear, which also greatly affects the opportunity of early education for infants. Most importantly, many early education courses of Red, Yellow and Blue are also cooperated with other education platforms, which makes Red, Yellow and Blue too dependent on education and difficult to make a breakthrough.
