Yesterday I was really very tired after being off duty. And I play with my phone and watch Bilibili which plays a horrible movie. And then play a terrible sound to got sleep.

  That day I didn't found a place for the phone, but fortunately, I didn't do watch more just hear the terrible sound. But in case of that, today evening, I will found a place which can be locked to put the phone into it to let it 'sleep' as I am sleeping.

   The second thing is about the 'u disk connector' I tried the Lenovo connector that works well under the same computer. And these experiments really resolved my doubt of the unmatch problem between computer and mouse.

    The last mission I'm not done with is the summary of Lesson8 for 'language in use '.  check that check that.
