The Sik Sik Yuen Wong Tai temple is a large complex, largely built early in the 1970's, for Taoist workshop. It is dedicated to Wong Tai Sin who looks after success in business and avoiding ill-health.
There are several different parts to the temple. The picture shows the garden of the nine walled dragons. On seeing the sign, we expected a garden with a wall around it, containing nine statues of dragons (or maybe a lot of tarragon). Instead, there's a garden, with a wall in it, decorated by nine ornate dragons, each one different from the rest.
We also visited the Garden of Good Wishes. A series of small temples wind around ponds connected by waterfalls (sadly turned off and being drained for cleaning during our visit). The ponds are full of fish and small grey tortoises.
