I has heard that one of my 'brother in Lab' ,Yang, has given up his PhD study after two year' tough experience in United States.

  I don't know what has happened to him, but I can feel that it, really, would take a lot of courage to make such a big dicision.

  Know what, that kinda thing flashed into my head a few month ago, because some situations were totally unexpected at all, even till now.

  However, I just don't have the courage to give up for some reason.

  Yang, my 'brother in Lab', I envy you.

  Wish your trip back home safe and sound.
