very glad to see your reply.
Thank you very much for your review of the code and found so many problems.
There was a conflict between the latest code and patch, I have corrected it
and provided a new patch (V65).
Waiting for your feedback.

Regards, Wenjing.

I corrected the ERROR message of GTT according to the link and the existing
error message.
Some comments and code refactoring were also done.
