Adopted Children

Having read in the news that an adopted daughter in the US has colluded with her children to murder her adopted father who fortunately was not killed though badly hurt with bricks etc. The father is now 80 plus while the adopted daughter is 40 plus with 3 children.  Just this morning I tried to invite my friend to a magnificent show from China and in the course of our conversation , he painfully revealed that his adopted son who graduated from Russia with a doctor's degree has repeatedly behaved in a way that is unbecoming of a son, very rebellious and uncooperative. It is a very big blow to him as his own son was long ago kidnapped and just disappeared or lost in the air. His greatest hope is to find someone to succeed him and his huge wealth. But he is very cruelly denied of this pleasure and their relationship is in the point of breaking off in the river of no return. I greatly sympathize with him though I do not agree to his idea of having an off-spring is the greatest duty of a man according to Confucius . I think to avoid unwanted worries be should have a worldwide outlook instead of trying to adopt a son why not donate his enormous wealth to worthy cause such as real charity and helping really needy people. But I think it is hard to convince him to be so generous and selfless.
