Young convergence refers to the process of children's transition from kindergarten to primary school. In our country, infant connection generally refers to the connection between the learning stage of the large class (or the last year of kindergarten) and the learning stage of the first grade of primary school. Young relationships usually last for a year.

Specifically, a year of young convergence usually includes the following stages:

1. Kindergarten class: This is the last year of kindergarten. In this year, students will learn some basic knowledge, such as cognition, language and mathematics, so as to lay the foundation for primary school study.

2. The first grade of primary school: In China, the first grade of primary school is the first year of school, and students will officially begin to receive primary education. In this year, students will continue to study basic Chinese, mathematics and other subjects, and gradually adapt to the learning environment and learning methods of primary schools.

To sum up, under normal circumstances, the year of young convergence includes the kindergarten big class and the first grade of primary school, totaling one year.
