According to legend, Yuan Tiangang, a Taoist priest, and Li, a half-brother, were famous geomantic omen teachers in China at that time. Li Shimin, Emperor Taizong, has just achieved great success. Due to years of war, people are displaced, fields are barren and the economy is depressed. He started the famous rule of Zhenguan in China's history, and implemented the policy of reducing taxes, preserving health, benefiting the people, practicing economy and opening up roads. The commoners came from humble origins and were in office for 23 years, taking agriculture as the foundation, which made the Tang Dynasty's economic development, social stability, political clarity, male farming and female weaving, and the people's prosperity and well-being. Soon, the Tang Dynasty saw a prosperous scene and ushered in the rule of Zhenguan. Emperor Li Shimin is prepared for danger in times of peace. For the sake of the Li family's hereditary dynasty, he asked Mr. Feng Shui to find the four pillars of a peaceful world for the Tang Dynasty: the emperor, Confucianism, Buddhism and Taoism. At that time, Li and Yuan Tiangang made suggestions for the stable development of farmland and the Tang Dynasty.

They were ordered to put the two pillars of the emperor and Confucianism in the inner palace; The Buddha pillar is in Wutai Mountain and the Taoist pillar is in Laoshan Mountain. Therefore, Li and Yuan Tiangang came to Laoshan for feng shui test, and when they saw that there was no eye of heaven and earth in Laoshan, they went back to the palace. After a few days back and forth in Laoshan, I continued to look for it with the gossip compass. As a result, I found the eye of heaven and the eye of the earth in the southeast of Cuobuling, and immediately returned to Beijing to live. Li Shimin was so happy that he ordered a temple to be built here some other day and named it "Huang De 'an".

Huang De 'an was brilliant for a while after its completion. A temple named "Nanting" was built in the eye of the sky. Guanyin is enshrined in it, and Li also wrote a couplet for Guanyin. The first couplet reads: Why did you sit down? Bottom line: Because the world refuses to turn back. There are no words in the horizontal batch.
