What's wrong with the world

Tweet

Recently, I pay more attention to the Gaza war from the internet,too many ordinary people dead from the war, children,women, elders...,I can not understand why there are such rediculous things hapen in this beautiful world, where has the mercy,kindness gone? we are human, but we kill each other. Fortunately, most of us live in a powerfull country, maybe we not happy with current situation, high housing fee, high living cost, unfairness, but we live safely in the world. Thanks for the people who are always protecting us.
