Filling both the left and right walls of the temple are the murals depicting Celestial Guardians. Each wall portrays 18 of these message carriers - a common Fujian theme. Of both male and female genders, the detailed figures each ride an animal and carry a unique weapon.
The artist known as Yeoh Boon Ngah the Hermit also painted several other murals in the temple, including the one above (detail shown), entitled "Hundred Sons and Thousand Grandsons." The level of preservation of these highly detailed murals painted over a century ago is quite impressive.
