Zhang Zian told his suggestions to Little Celery and Wang Yaning. As for their final decision, it wasn't any of his business. After all, letting children take responsibility for their own actions was a necessary part of growing up.
Little Celery and Wang Yaning discussed for a bit longer. Little Celery was strongly in favor of Zhang Zian's advice. In her opinion, Mr. Store Manager understood pets the the best. Wang Yaning couldn't make any reasonable objections. They finally decided that they were going to tell their school that they would try raising Djungarian hamsters and lop-eared rabbits for their animal raising class.
Wang Yaning, as the student representative of biology in her class, was also responsible for writing up the reasonings for their decision in their report. However, she had gathered enough information from Zhang Zian and was confident that she could complete a well grounded report.
