The 21st Century Experimental Kindergarten is the first first-class private kindergarten in Beijing, and the earliest private boarding kindergarten in Beijing. The management of the group has allowed the 21st Century Experimental Kindergarten to be distributed in various areas of Beijing, and even have branches in Chengdu, Changchun, Changsha, Suzhou, Tianjin and other places.

Enji No. 1 Kindergarten is the earliest kindergarten of the 21st century experimental kindergarten, which was established in 1995 and is only separated by a wall from the public Enjili kindergarten. Many parents who are unable to apply for Enzili Kindergarten will put their children's enrollment hopes in Enji No. 1 Kindergarten, 21st Century Experimental Kindergarten. Although Enji No. 1 Park is the oldest park in the 21st century, all facilities are set up in accordance with the environmental protection and safety standards of the kindergarten, indoor floors, toy cabinets, building block toys, game tables, and outdoor large-scale combination toys are all made of logs, avoiding the use of lacquer, and the walls are also using environmentally friendly paints. The kindergarten is equipped with a sand play area, a water play room, a plantation, a multimedia audio-visual library, a game therapy catharsis room, a piano room, etc., to meet the children's entertainment, learning and life during the school period.

In the 21st century, there are regular classes and international classes, and the biggest difference between the two is the time it takes to learn English. The English learning time of the ordinary class is smaller than that of the international class, and each class of the international class is equipped with a full-time foreign teacher and a Chinese teacher, and the way of bilingual teaching is implemented. There are many activities organized in the kindergarten every year, such as Halloween and New Year's garden activities, June Day charity sale, Dragon Boat Festival rice dumplings, Mid-Autumn Festival moon cake making, etc., and puppet shows, sketching, picking, etc. Although the kindergarten also has artistic talent courses, such as dance, piano, singing, etc., its talent courses are not as set up as Little Oxford Bilingual Talent Kindergarten.

Enji No. 1 Kindergarten mainly enrolls children from 1.5 to 4 years old, with 6 classes, young children in the form of small classes, and there are also weekend parent-child classes. The enrollment situation of each park is different, and some branches give priority to the enrollment of nearby community owners, while Ruyi Manor does not have much restriction on the enrollment of young children.

However, in recent years, some parents have reported that the tuition fees of the 21st Century Experimental Kindergarten have risen year after year, with the ordinary class about 5,000 yuan a month and the international class at 13,000 yuan a month, but its hardware facilities and teacher configuration have not changed much, only the tables and chairs have been replaced or the English learning time has been increased, and the tuition fee is not proportional to the value. If you pay more than half a year's tuition at once, there is a certain discount on tuition. If you want to choose the 21st Century Experimental Kindergarten, it is best to call the park in advance to confirm the tuition and other conditions, and the 21st Century International Class is not much different from the ordinary class, and it is of little significance to enroll in the International Class.
