1. There will be another short talk this Sunday, we will fetch a document from China Travel to help passing the custom
2. I still want to buy a timer remote for my Canon 450D, my notebook is not so reliable for this purpose
3. Camera backpack: I guess I will settle for something slightly smaller, since I won't be bringing out so many lenses for this trip or even later stargazing trips. I want something more compact and useful for daily purpose during the trip, like to store a bottle of water and some personal stuff.
Sounds like a Fastpack 350 is a nice idea.
4. Mobile phone card (add value)
