闲居遣怀十首

唐·姚合

                                                                                    身外无徭役，开门百事闲。

                                                                                    倚松听唳鹤，策杖望秋山。

                                                                                    萍任连池绿，苔从匝地斑。

                                                                                    料无车马客，何必扫柴关。
