Organize your notes and find a note about the old boy's teacher's idea of operation and maintenance. In fact, the old boy teacher in each class will speak some of their own work and life of understanding, but the teacher did not have a good topic name, is not very catchy, like Alex Teacher's heart chicken soup has a reputation.
The following content is derived from my class in 21 and watch phase 19 video. Some are the teacher dictate, some are the teacher blog content, perhaps some repetition, but this kind of spiritual food more fermented several times, taste more alcohol.
Some of the content of the teacher bar is said a bunch, but I also remember a few words, relatively simple, forgive me,:-). In any case, give the 23 phase that is already on the runway ready to take off, as well as the 25 phase 26 phase that is being assembled, and even the unknown approaching n phase.
I am just throwing jade, who has not forgotten to send out.
