Actually, i have got used to this busy life style, large amount of documents and papers and upcoming experiments. To some extent, it seems that the true meaning of  the life has got far and far from me. It is a pity. Life is not only experiments and papers. We have family and friends. We should share our time with them to enjoy ourselves.

Occationally, i thought one sentence, that is life is clourful, life is meaningful and life is wonderful!
