Ching Chung Koon is a Taoist temple first established in Kowloon during 1950. A permanent temple was eventually built in Tuen Mun during 1960 and a branch temple at Kowloon was established in 1974.  As this card was mailed in 1983 (with stamp and postmark), and knowing where Castle Peak is, we can tell you this is the structure in Tuen Mun.  The card has a sticker on the lower right front corner.  Grade: 4
