Doing PPT

Tonight, I sleep late again for the reason that I must finish the ppt to discuss with my group members tomorrow.

Now, it has been 1:17 AM. Is it a sleepness night? I feel my back pain and my thought is confused.

Above all, I finished it! and I can update my blog after a long break.

Recomended a fair-sounding music, which is perfomanced by piano, Be in love with butterfly, 蝶恋，(a theme music of RPG Legend of Sword and Fairy 仙剑奇侠传，这是大宇公司出品英文名字，不是我自己翻译的)
