Today, I changed my nickname of YMBBS from "Dating With Beethoven" to "Mature, sincere, and doing without asking for rewards." The previous I used for more than two years. The changing doesn't mean I give up the original intension I set 2 years ago. On the contrary, I hope to hold it tightly in my hands, in my mind. But it is more important for me to get mature, get along with friends sincerely, and the most important is to do things without asking for rewards. I hope in the future, I will become a more complete man and responsible for myself.
