Han Chengen is a wacko tacko. Absolutely cuckoo! His head needs to be examined. Why on earth would he think killing some one's child means getting revenge for them?
If eventually his wife regains her memories back and find out that her dear loving husband has been trying to harm her own daughter... She will not forgive him
Is Han Chengen stupid or getting old? He provoked Gu Jingze first and now he is feeling panicky and vengeful, then blames it on Jingze! What a dumb fool..
