Dear Peng, The first few tutorial programs <https://www.dealii.org/8.5.0/doxygen/deal.II/Tutorial.html> demonstrate how to query basic information related to the mesh. The documentation for the triangulation <https://www.dealii.org/8.5.0/doxygen/deal.II/classTriangulation.html> class and also the GridTools namespace <https://www.dealii.org/8.5.0/doxygen/deal.II/namespaceGridTools.html> highlight some of the fundamental information that you can extract from the grid. Also, the accessor classes (e.g. CellAccessor <https://www.dealii.org/8.5.0/doxygen/deal.II/classCellAccessor.html>) document what information you can get from a cell and, for example, step-14 <https://www.dealii.org/8.5.0/doxygen/deal.II/step_14.html> shows how to query a cell's neighbouring cells.
I hope that this helps you.
