我上初三的儿子因为打架伤人受过处分。没想到,在后来的许多活动中,包括区、校举办的各种能力竞赛,学校认为他曾受过处分,说是怕他影响学校的名声,不允许他参加。孩子很失望,也很生气。我们有心帮孩子解开这个疙瘩,又不知有什么正当的理由。请问,我们该怎么办?陕西郑欣郑先生: My son on the third day was punished for wounding. Unexpectedly, many subsequent activities, including competitions in various capacities held by districts and schools, considered that he had been punished. He said he feared he would influence the reputation of the school and would not allow him to attend. Children are very disappointed, but also very angry. We have the heart to help children solve the knot, but also do not know what the proper reasons. Excuse me, how should we do? Shaanxi Zheng Xin Zheng:
