周而复始 Cycle ; Full Circle ; Repete ; go round and round

他周而复始 It goes full circle

周而复始的 round ; Back and forth

周而复始的经济 The Circular Flow

它们周而复始 They Turn and Turn around

它周而复始 It goes full circle

来来回回周而复始 Has come and gone away

一次又一周而复始 Turning and returning

周而复始的前行 Moving forward in cycles

周而复始的季节呀 My tears
