Marc, you may try calling Zierer @ 866-788-1100. Once you enter China, you can travel all over within China with one entry Visa but when you leave you can't return again without a double entry. I have no idea about walking into Chinese embassy to obtain?? (got ours through Zierer but they've always been helpful on the phone with questions).
