The colorful gods adorning the ‘Five Doors’ on the north side are painted in careful detail in strong, confident strokes. Fading over the years also impart an aesthetic antiquity to the paintings.

The history of door gods stretches back to the ancient Shang Dynasty (c1783 - c1134 BC). Shentu (on the left) and Yulei (on the right) are the two gods most often depicted on temple doorways. The Martial General, a more recent door god, is a synthesis of Chin Shu-pao and Hu Ching-teh - two virtuous generals of the Tang Dynasty. They were introduced, as their power was believed strong enough to cast out evil spirits and demons, ensuring the purity of the altar within.
