Hello Youqi,

Thank you for answering my questions and addressing my comments.

That would be sufficient. In case someone asks to know in this 
direction.

I just wanted to say a few words that in future we have plan to explore 
and also if you can just comment on it. Certainly, this is not for your 
current presentation to do this.

Thank you for this information. That is Ok.

Thank you.
