Hi, friends. Today i talk about something with XingLong, who is a good good friend in our laboratory. We just think that "mm" is not a good thing. We should not approach it. In fact, when you feel solitary, you will think that. ha ha, now i am "" . I just know it nothing. Teachers' Day is also in today. I just sent two series of flowers, which my teacher said i just like proposing to her. ha ha,it is smiling. Okay all that, bye.
