Being the most fundamental social relationship，a harmonious neighborhood is the foundation for a harmonious society where the concrete barrier featuring living within hail but never visiting each other is such a common scene in modern cities. It is thus a topic of urgency as to how to break such a barrier and achieve harmonious neighborhood self-governance in the context of the social governance model featuring the residential self-governance and multi-body participation. From 2006，Kangleli Community of Guang'anmennei Sub-district launches the neighborhood festival activities with a different annual theme，aiming at creating a sound air of friendly，loving and cooperative neighbours. This very platform of the“neighborhood festival” has enabled Kangleli Community to promote the building of a harmonious community with considerate，warm and comfortable neighbours and create an air of unity，mutual assistance，civilization and peace，allowing the residents to revive the past neighbour love. This article aims at presenting some experience for reference to other regions through deep study on practices and achievements of the neighborliness culture building of Kangleli Community.
