JIT production mode realizes the overall flexibility of the system through the operation of the organization and the high ability of employees.Note: Be sure to connect the data cable with the computer when entering DFU for operation.　　女县长鞠萍率领的工作队正在夹皮沟开展土改，深夜遭到奶头山匪许大马棒的突袭。危难中通讯员白茹突出重围向牡丹江民主联军二团部求救，途中被进城买粮食的团部炊事员杨子荣所救……
