The two servers for your domain have different versions of the zone.

ns1.dns-diy.com has serial number 3556 and the record:

s3.xxfy.duowan.com.  300   IN CNAME s3-duowan.xxfy.kunlun.com.

ns2.dns-diy.com has serial number 3551 and is missing that record, so it 
uses the wildcard.

So talk to your DNS hosting service and find out why their servers are 
out of sync.
