One interesting thing....

At the Sheraton Jiuzhaigou, I tried using the safety deposit box. Followed the instructions, I successfully set my combinations, lock and unlocked. After that, I expect to use this same combinations as any other hotels I accustomed to. Well, this one was not. The combinations were only used ONCE. Once you have locked it, your combinations were no longer in use. And guess how to open it? It was a secret - all the staff knew, use "0#" to unlock. LOL!!! So, what good would this safety deposit box to me? Very funny indeed. The staff was so serious explaining to me how it worked. ;-)
