Introduction to the ancient well: The ancient well on the street after entering Zhongying Street was built by the Hakka people who moved to Sha Tau Kok to open up wasteland during the Kangxi period of the Qing Dynasty. It has a history of more than 300 years and is a drinking water source for local people. The folk song of "walking together on the same street and drinking from the same well" is still popular among people on both sides of Zhongying Street. "Drinking water reminds one of the source." The ancient well has a nurturing grace for local residents, and it also involves the nostalgia and family affection of the residents living on both sides of Zhongying Street. It is not only a witness to the historical development of Sha Tau Kok, but also a historical witness to the formation and development of Chung Ying Street.
