What do you think is a better song to sing when you go to an old people's home to perform?

To go to the elderly home, I think we should start from the elderly favorite songs, because this elderly will be more interested in, especially compared to their own singing pop songs, easier then. I recommend singing red songs, such as "Oriental Red", "Singing of the Motherland" and so on, these are familiar songs to the elderly, more able to let the elderly into their own songs.
