That green bull was originally a magic bull in heaven. Because it did not abide by the rules in the heavenly palace, the Jade Emperor punished it by banishing it to Yunmeng Mountain to plough the farmland. It had long known that the Queen Mother planted Lingzhi (Ganoderma lucidum, or Reishi mushroom) in Yunmengshan Mountain. At the thought of this Lingzhi, its mouth watered. When Sun Bin sowed with a drill, he held its nose tightly. He was also casting spells, so the bull didn't dare to mess things up. Today, before sowing with a drill, the young attendant promised two conditions. It was determined to eat this millennium Lingzhi. As soon as it reached the edge of the northern cliff, the green bull stretched its neck to swallow the Lingzhi in one gulp.

After swallowing the Lingzhi, the green bull felt hot and dry all over his body, thirsty and unbearable. It suddenly recalled the water in the Duanwang Lake at the foot of the hill. Regardless of the repeated dissuasion of the young attendant, it ran down the north cliff to the lake and drank all the water in the lake. But it still felt thirsty. It could recall other places where the water was available.

Gradually it died of thirst and turned into a hill, which is current Golden Bull Ridge.
