2012.02.27 Today is sunny day. I haven't written the notebook for a few days. I belive that if I write the notebook every day , my English will improve. It is hard to insist on doing something, although know it is good. I have to remind myself. Today our boss issued two goals. The first is First Passed Yield>99.9%,the other is increase the efficiency of labor by 10%. We should do our best to achieve the two goals.
