The construction of teachers' Party branch promotes grassroots governance in colleges and universities, which is not only the centralized embodiment of the implementation of "strengthening the overall leadership of the Party", but also the basic path of establishing a clear guidance of "all work to the branch", and the inevitable requirement of playing the role of "leading grassroots governance". Aiming at "triple unicom" to perfect college grassroots governance mechanism, basing on "triple training" to promote college grassroots governance work ability, and emphasizing on "three ways" to raise college grassroots governance level, are important explorations in solving the current Party "hollowing out" grassroots governance structure in colleges and universities, and the separation of Party affairs and business work in teachers' Party branches.
