Chong Har Ching Ser, Taoist temple in North District, Hong Kong.

Chong Har Ching Ser is a Taoist temple on the former Huanggang Hill in Fanling, now part of Fanling town centre. The present building dates from the 1950s and, seen from outside, has the layout of a small two-hall courtyard house. It belongs to the Xiantian Dao branch of Cangxia Cave in Qingyuan, Guangdong, and honours Guanyin, Lü Dongbin, Beidi, Guan Yu, the Three Pure Ones, Huanglong Zhenren and Confucius.

Chong Har Ching Ser was founded in 1920 by Zhu Hanting as a branch of the Cangxia Cave of Qingyuan, Guangdong, belonging to the Xiantian Dao sect. The present building dates from the 1950s. It keeps ties with the Feixia Cave temple in Foshan and with Xiantian Dao communities in Southeast Asia.

The temple belongs to the Xiantian Dao sect and is a branch of Cangxia Cave in Qingyuan, Guangdong. Its main celebrations are the Sanyuan festivals and the Ullambana festival. The name "Cangxia" later gave the neighbouring Cheung Wah Estate its name by homophony.

The temple can be easily reached via Fanling MTR Station on Pak Wo Road, which provides good connections to the rest of Hong Kong. Public transportation makes visiting straightforward, and the area is well-connected for day trips.

The housing estate next door, Cheung Wah Estate, was first planned as "Wong Kong Shan Estate" after the hill. Because that name recalled the 1911 Huanghuagang Uprising, the Housing Department instead took the sound of the temple's name "Chong Har" and named the estate Cheung Wah.
