Do need to show personal financial statement from the bank?

I am flying to Germany on Oct 2013 holding a visit visa from a Philippine passport. It is my second time to take transit layover to Beijing when I fly to Germany and the same when I come back to the Philippines. When applying for a transit G, do I have to submit other than my confirmed plane fare, a passport with an immigration stamp from Beijing that I set foot at their airport last Nov and Dec. I would like to apply at Cebu, much nearer to my hometown Davao City rather than flying to Manila. This time with a 10- hour airport layover at Beijing, it is nice to take a short tour to China's Great Wall. Thank you in advance for clarifications on my queries.
