Chinese visa places of travel, duration of stay
I am going on a cruise from Hong Kong and while I have applied for multiple entry visa(6 months) I only put down Shenzen and Sanya in China as places to visit and longest duration 1 day. I now wish to extend my holiday and travel to Guangzhou, Shanghai, Suzhou and Beijing. My longest stay will now be around 10 days. Is this going to be a problem for me when I travel?
