Dear Le Lina,
1. Firstly, what is "exhibit product"?
In case you have any new product you want to show. 2. Secondly, I'm unable to download and print the invoice after doing my registration, I am not so sure whether it was my false or due to your server.
It is ok, your registration is in the list. Thanks a lot
3. And lastly, I would like to reaffirm that it is possible for me to pay the conference fee equivalent in Vietnam Dong on the commencement day of the conference enclosed with my invoice.
The fee can be charged in cash (Vietnam Dong) can pay at the registration desk at the begginning day of conference.
Best regards,
Pham Thi Mai Thy
