Use the five numbers 1, 3, 5, 7, and 9 to form a five-digit number, so that the sum of the five-digit number and its anti-sequence number (such as the anti-sequence number of 1234 is 4321) is as large as possible, then the maximum value of the sum how many.
用1，3，5，7，9这五个数字组成一个五位数，使这个五位数与它的反序数(如1234的反序数是4321)的和尽可能大，那么和的最大值是多少．
