Whatever I try, the gel still can't appear. I don't know what is happened, maybe gel doesn't like me. If gel still won't appear, I would do the experiment all the time until the gel appears, otherwise I would change direction of the experiment, worst of all I would study the third grade. J.J Ruan always gives me a lot of experiment to do, I believe that not me but the others also have to do the same thing, but I think if I do it which have no exact experimen method, how will I get the achievement from it？ Pro. Ruan often imputes the experiment failure to me, but he forgets that besides my problem he also has some problem from my research, and he sometimes even likes say some unpleasant words about me. I really can't tolerate it. Oh, who can help me？ --
