一段支撐起大半個世紀城市發展建設的重要歷史，一群用血汗、勞力和無法告人的艱辛奠基城市公共衛生的人們，一段在當時無法言說，如今也只想遺忘的過去。

​

The story of how a group of dedicated and hardworking labourers contributed to the building of a city sewage system for nearly half a century. This is a part of history that people failed to speak about in the past, and had intended to forget in the present.
