Traveling from Japan to Egypt through Beijing Capital Airport

I am an Egyptian passport holder traveling to Egypt from Osaka, Japan and I have to stop at Beijing Capital Airport for about 6 hrs to take my next flight to Cairo, Egypt. My daughter (less than 1 year) was born here in Japan and has only Traveling document, issued by Egyptian Embassy in Japan. Do I need to have Egyptian passport for my daughter to only stay in Beijing Capital Airport with her parents or the traveling document is enough? Thank you
