LP prefers KeKe to watch the songs on IPD rather than DVDs. I ordered some popular DVDs for Keke and she likes watching. The problem is that Keke can play the music on the IPD and can play it again and again, but Keke has to bother LP to play the music on the DVDs. Keke showed me once on the IPD, “放大点,” she said then pressed the window corner with the arrows of the video clip to zoom out. It was very interesting.
