Have been considered for a few days, finally, I decide to join this activity.
Sunday morning, I woke up around 6am, waiting for 199-bus, and then taking MRT to Chinatown.
Afterward, a senior, Jie Ting, accompanied me to a residential area that is lived by those old folks that living alone. Singapore government has provided them a single unit in those 21-storeys flat, with S$100 allowance monthly. The environment in the flat is similar to the scene in the Hong Kong drama series. Compare to those homeless old folks, they are luckier.
