these last days These last days I was busy installing the equipment about grand soil experiment. Actually, I would like to say it is a challengeable task for me and I believed that I could not finish the task by myself. I therefore asked helps from people around me. Fortunately, I eventually found two friends who can be willing to help me. Then, we made plans and started gradually completing the task we set. From the whole process, the thing was not always as much complicated as we thought and just persisting in doing it. Meanwhile, I had gotten much more confidences from the process, and I believe that i could be more competent to control or do similar jobs or even more challengeable jobs. it is true fact that I could not finish the whole installation without the help of them. Now I feel thankful for them and I have to say that a friend in need is a friend in deed.
