The Dragon Head Temple was originally called Tayantou (Pagoda Rock Head) because the Pagoda Courtyard of the King of Immateriality used to stand on the loess slope under the rock. One day in the Tang Dynasty when Li Shimin came to Mianshan Mountain to pay homage to the mountain, he saw two dragons show their presence; hence he renamed it Dragon Head Temple. Now the area around the Dragon Head Temple has more than 20 tourist attractions, including the Temple of Guan Yu, a famous general in the Three Kingdoms period (220-280).
The Hundred Dragon Screen In the third year of the Wude reign period of the Tang Dynasty, Li Shimin suffered a great setback in the fight against Liu Wuzhou in the Sparrow and Mouse Valley at the foot of Mianshan Mountain, and he was in danger. All of a sudden, a peal of drum came from the sky, and 108 warriors in white war robes appeared from behind the Tang troops. Each of them was very intrepid. After a fierce fight, the troops led by Li Shimin defeated the enemy, and the 108 warriors in white war robes immediately turned into dragons and flew to Mianshan Mountain. Later Li Shimin got to know that it was Thunder God who came to help him, so that he had the Hundred Dragon Screen set up.
