On the morning of November 26, 2019, Qin Ling, secretary of the 102 and 107 workshop branches, gave a special party class to all party members in the 305 meeting room. Qin Ling led all party members to learn the "three meetings and one lesson system" and the "three not to forget". After the study, the party members put forward their opinions and suggestions on future party building activities of the branch.

The "three meetings and one lesson" system is an effective organizational life system established by our party based on the historical experience of self-construction. By studying the "three meetings and one lesson" system, not only has all party members deepened their knowledge and understanding of the party's "three meetings and one lesson" system, but it has also effectively strengthened the discipline concept of all party members.

"Three unforgettable" is the original intention of the Chinese Communists. Through study, party members have deeply realized that: do not forget the original aspiration, know the mission, only be able to take it, and only have to endure.
