All together this forum today, main purpose is to study and implement in depth General Secretary XI Jinping on \ng education, studying and implementing theCentral and autonomous region Party Committee and municipal party Committee \ducation Symposium, arrangements for district-wide learning education. The following, I would like to stress four points, mainly talk about \ning\ng\ople really figure out why, what to learn and how they learn, what to do, how to do it, eventually reached little success, is also leading a lesson in party lecture.

To realize \ning practice activities and education is the education of the party's mass line, \e-three\cial education was another important practice in implementing the requirements of strictly administering the party. Comrade XI Jinping pointed out: \deployment of ' doing ' education, is to promote the inner-party education from ' critical few ' their expansion into the vast number of party members, extending from the concentrated education to regular education. \handle party, strictly administering the party, and has carried out the party's mass line education practice and\e-three \cial education, but focus on the leading cadres above the county level.
