SINGAPORE - When 80-year-old Liu Xiao Zhong died in his sleep on a cheap mattress on the floor of Mr Lee Cho Poon's one-room rental flat in Ang Mo Kio in 2011, Mr Lee arranged his funeral, mourned and paid his respects to him.

Four years later, in 2015, another elderly man, Mr Lee Wen Qiang, who was in his 70s, died in the same flat. Once again, Mr Lee Cho Poon helped arrange the funeral, mourned for the dead man and ensured his ashes were placed in a temple.
