菠萝山（英语：Por Lo Shan）Hong Kong version of the mini Grand Canyon

Por Lo Shan is a hillock in Tuen Mun, Hong Kong with a height of 121 meters. It is located between Shan King Estate and Liang King Estate and is known by many as Tuen Mun Backyard. Suburban maps published by the government also clearly indicate the location and height of Pineapple Hill. However, in the private sector, "Pineapple Hill" is often mistakenly referred to as the Qiu Ling area along the old military vehicle road in the Aoyama gunboat area. In recent years, people were found to have a unique view of the Grand Canyon of Hong Kong. They attracted many people to visit the area for picnics and became the "back garden" of many Tuen Mun people.
