"一个是亲生的儿子，一个是领养的儿子；一个是自己的骨肉，一个是杀死自己骨肉的凶手。身为母亲，她将如何化解丧子之痛，敞开胸怀去接纳和拥抱那个杀死自己儿子的儿子？这其间，她经历了什么？她又超越了什么？ 　　“我之所以选择宽恕和接纳你，不意味着我不爱我的儿子。相反的是，因为我对他的爱，所以我想把这份爱传递给你。事实是，他走了，你还活着。”—母亲黄品萱。" "One is her son, the other is her adopted son. One is her own flesh and blood, the other is the murderer of her own flesh and blood. As a mother, how could she alleviate the suffering and open her heart to accept the son who killed the other? What did she go through? 　　“I choose to forgive and accept you not because I don’t love my son. On the contrary, I want to convey my love to you because of my love for him. The fact is, you are still alive and he is not anymore,”said the mother Pinxuan Huang."
