怎么维护老客户？
像朋友，像家人一样，做好客情关系。
My dear friend John, I wish you are well and happy. Take care of bad stress at job and in your life. Your body and your mind are precious and all your life you will be the only one to suffer if you do not take enough care. Every day take few minutes to look at a child smile, a flower, a butterfly, they are the way the angels have to touch us.See the angel of our family....
