Four to focus and work hard to resolve. Comrades, the above is what I give you guidance in the new Constitution. Hope every Member of the party to pass the tutor, deepen our understanding of the Constitution in the party's guiding ideology advancing with the times, consciously link their own thinking and practice, after careful study, read and carefully understand, think, relate, apply what they have learned. Not only runs through the mass line of the party Constitution to learn the new educational practice all the time, but also to harvest as a good starting point to learn, study and work to do better in the future, and strive to create a new situation for school education contribute their混凝土简支梁桥内力计算
