Han Chengchi started talking when he was just one year old, while Gu Enen had just learned how to crawl, and the two babies occasionally hugged each other and played, never fighting over toys.
Han Chengchi and Gu Enen began to truly play together after Gu Enen's third birthday. Both children could talk and had learned to communicate, so they played house—Gu Enen as the bride and Han Chengchi as the groom. This game continued for a year until they both went to the same kindergarten.
At that time, Han Chengchi and Gu Enen didn't know what child betrothal meant, nor did they understand what being a bride and groom entailed. Yet, they understood that they would be together in the future. Thus, in kindergarten, they were inseparable, and then through primary and junior high, understanding what child betrothal and being newlyweds meant, they learned to hold hands and kiss. Then they went on to high school and naturally slept together.
