What will my brother do after putting the secret in his schoolbag and putting him to sleep?

The author wrote that his brother let his brother sleep and kept a diary for four pages. Here I mentioned Jiang Tingqi's schoolbag, which is still with my classmate Chen, and his diary is in the schoolbag.

Sun Weiwei, the secret author in the schoolbag, is the future publishing house of the publishing house. This is a novel describing the growth of teenagers in a difficult situation in the new era. Jiang Tingqi, a persistent, simple and kind-hearted fifth-grade student, was trying to tell her mother the good news of being selected for the composition competition, but news came that her mother had an accident because she saved people.
