   function payIn(uint holdTime) public payable{
       require(msg.value > 0);
       HoldRecord newRecord;
       // When we lock up our money , In fact, the amount is locked ownerAmount Inside , Without locking in our own address 
       // This will lead to the theft of funds , Use 5.0 The above version will avoid this problem 
       newRecord.amount+=msg.value;
       newRecord.time=now + holdTime;
