In the days when Nga Tsin Wai still had a fish pond, the environment was beautiful. The nearby land was lush and green, with watercress fields in front of the village (now San Po Kong). San Po Kong was originally a beach which was only developed into a vegetable field at a later stage. When Ng Sui Mo was a child, he liked to jump into the nullah (eventually known as Kai Tak Nullah) to swim. The water in those days was very clear. This was especially true after heavy rain. The bottom of the nullah was paved with soft mud and children dived directly into the water from its sides. There were eels and carp in the nullah back then. Carp appeared mostly on hot days. Ng Sui Mo tended to lay his whole body in the nullah, trying to catch the fish by using his body to squeeze them onto dry land. What a funny sight he must have made!
