林村鄉始於宋代，幅員遼闊，有二十六條村。許願樹位於林村鄉天后廟右旁，遠望五彩繽紛，恍如長出奇花，其前身為一大樟樹，附有伯公神位，由於年代久遠，枝幹隨之枯萎，遂成為通心樹，據傳有一善信，其子入學毫無寸進，經拜通心樹後智慧頓開，學業有成，因此四方善信慕名而來，還吸引不少外國遊客，由於許願者多靈驗，故每逢假日，春節期間，人群擠得水洩不通，今更成為香港旅遊點之一。
Lam Tsuen is formed in the Song dynasty with a vast territory covering 26 villages. The wishing tree is located to the right of Lam Tsuen Tin Hau Temple. It was colorful as a flower when observed from afar. The wishing tree was two camphor trees with an altar worshipping Tudi (God of the Soil and the Ground). However due to aging its branches withered and trunk emptied. The story goes that there was one faithful worshipper whose child had bad performance and no progress in school, after worshipping the tree, the child suddenly became clever and had good results in school. Such that, many people were attracted to visit this place and worship, including foreign tourists. The whishing tree is now one of the tourist attractions in Hong Kong. During holidays and Lunar New Year, the place will bustle with people and visitors.
