Feng Shui and numerology play an important role in Chinese culture.  Legend has it that Wu Kau Tang, initially named ‘Wu Kwai Tin’, which literally means ‘Tortoise Field’, was renamed so because of the negative connotation attached to tortoises; villagers in the New Territories replaced ‘Kwai’ with ‘Kau’, taking the auspicious meaning of the dragon and phoenix.  Today, around Wu Kau Tang there are stone tablets with markings that refer to ‘Wu Kau Tin’.  The trail also features a hill fire lookout, which looks out on the entire Sha Tau Kok Hoi, including Yim Tso Ha Egretry, A Chau Egretry, mangrove beds along Luk Keng coast, fish ponds, and paddy fields.  The vistas of mountain ranges on the northeast of Plover Cove Country Park also come into sight.  The beauty of the landscape aside, the trail offers glimpses of villagers’ wisdom of making use of raw materials around them, as evidenced by Castanopsis on the stairs – back in the era when food was scarce, villagers filled their stomachs with congee cooked with milled fruits of Castanopsis, whose local plants are still easily spotted around the area.
