show's notebook entry: Sep 25, 2010 Today is a bad day for me. After a phone of one client ，I feel very bad，I will am crazy because of that thing. He said the product has wrong,and he wants to return it back us. But in fact he does't use it for a long time. So only if he can give some time to us,we will solve all the problems soon. Now a problem I must to solve is trying to placate the client,and I also hope to solve all problems quickly,then let the client be at ease.
