Aging Population

Today, I went to Yau Ma Tei to interview about the problem of aging population. Before interview people, I thought interviewing people was easilier than investigation of the questionnaire to people. However, when we asked someone worked in department store, almost of them refused because of they were working . Luckily, some of them were very kind, they answered our questions and provided many information for us.
In this group work, I have learnt how to invite and talk with a strange people. I think I need to be more initiative for talking with a strange people next time.
