The murals on the four walls of the temple were repainted more than 20 years ago by the master painter Fan Li-shui, who was regarded as a "national treasure." Exposed day after day to soot and smoke, sun and wind, the paintings have grown dark and indistinct and are starting to flake at the bottom. Repairing these will take several months; it's no small project.
保安宮正殿四周的這些壁畫是國寶級大師潘麗水於民國六十二年所畫，由於日復一日的煙燻、日曬和風塵變得非常黯淡，底部也有許多剝落，估計完全修復不是小工程。
