Little Lin Ke, a second-grade student, wore two braids and held the book in his hand. He shook his little head and said seriously, "Qing Qing Zi Jin, soothing my heart." "Chirp" the little boy at the same table pouted and kissed Lin Ke's pink and tender face. Lin Ke looked at the little boy, and then continued to recite "Qing Qing Zi Jin, my heart is full of joy." "Chirp" Lin Ke's face was kissed again. "Zhong Zijin! Why do you keep kissing me!" Lin Ke pouted his cute little mouth and looked at the red-faced Zhong Zijin next door. "Lin Ke, I've kissed you twice, so just stop reading."
