About disaster I believe there will be more and more disasters in this century,but I also believe man can conquer the nature. ‘can’ means stabilization or calm down, you will find a method when you calm down,we can't change ourself when the society changes. I do believe, no matter how big changes have taken place outside,As long as we creating value for our family,society,future generations and all of the employees, we will still persevere in it.
