Let +x+ = Xavier's age when they go married
+x+%2B+4+ = Yifei's age when they got married
( this is true because the difference in their ages never changes )
----------------------------------------------------------------------
+x+%2B+37+ = Xavier's age now
+x+%2B+4+%2B+37+ = Yifei's age now
------------------------------------------
+x+%2B+37+%2B+x+%2B+41+=+120+
+x+%2B+78+=+120+
+x+=+42+
and
+x+%2B+4+=+46+
Yifei was 46 when they were married
