Most of the residential buildings on Dongguan Street are modern brick wood or brick concrete structures, and the brick walls that need protection generally lose their structural strength, making reinforcement extremely difficult and complex.
The special urban texture and layout of enclosed courtyards also pose safety hazards such as fire and waterlogging.
The interior space of buildings generally has a small depth, high and low levels, and dense partition walls, making it difficult to integrate with modern functional formats and requiring systematic protection, repair, and renovation.
