For murals and other features that involve the outer appearance of a building, such ascarvings, beams, windows and other painted parts, Wang Chen-hua holds that unless the craftsmen really understand what they are doing, it's better to do nothing, because once new paint is applied the temple's old aura is lost.
王鎮華也覺得彩繪事關建築物的門面，在各種維修措施中，凡是塑像、壁畫、梁架、窗櫺等上彩部分，如果沒有真懂的匠人專家，最好先不要動手，因為一上新彩，整個廟宇的古樸氣質全沒了。
