Hiang Tong Keng Tua Peh Kong Association (Hiang Tong Keng Temple) was founded prior to 1911 and carries a history spanning more than a century. Once located along Coldstream Avenue, the temple was relocated to its present site at Tampines Link in 1993. 

In 2000, under the guidance of Master Leung, a Scripture Chanting Class was established to nurture the study and practice of Taoist teachings. This was followed by the temple’s first Taoist Ordination Ceremony in 2002. Since then, Hiang Tong Keng Temple has nurtured multiple generations of ordained Taoist priests and remains committed to the preservation and transmission of Taoist traditions through its rituals and scripture classes.

贒當宫建于1900年至今已有百多年历史, 原址在哥士林道一带 Coldstream Avenue (俗称寮里园), 锌板所建的一间小庙，让村里的善男信女烧香膜拜,祈求合家安康，1957年向政府注册贒當宫寮里园联谊会,成为合法宗教团体。由于城市重建计划的影响,本宫于1993年搬迁到旧淡滨尼路门牌93号临时庙址,并筹款重建庙宇，1997年举行新庙落成及晋宫升座大典。

本宫在2000年，香港蓬瀛仙馆梁德华道长的教导下，开设了贒當宫誦经团。习经礼忏,增进道教知识与修养,尊师重道的精神。2002年，贒當宫举行了本宫的第一个入道仪式。近几年，本宫经忏团在本宮主席郭宗寶和经忏团团长谢国华道长的领导下开办了新的经忏班栽培下一代的道教徒。经忏团也以社交媒体的方式分享道教知识与对想多了解道教的道教徒互动。
