I slept at the company for about three days. In fact , I did't sleep enough. Today, when I arrived at the office from the company lodging. There's an email from anyone who said there are serious problem in my module. The receiving list included our top president and executive. I wrote that problem was my fault and resolved. And I didn't forget saying sorry. Then, there's another big issue about appying animation effect. Mr. Min wasn't kind so it's hard that I used his module interface. In the evening, I could make it finally. So, which issues will appear in future?
