Introduction to Zhenyan Avenue: Zhenyan Avenue is 9 meters wide and 90 meters long. There is a 3-meter-high stone at the entrance of the avenue, on which the words "Zhenyan Avenue" are engraved with Zhao Puchuti. Six stones are evenly placed on the central axis of the avenue. Each stone is engraved with words on both sides. The words on the front are "Six-Character Great Ming Mantra", also called "Six-Character Mantra". This mantra is the subtle original mind of Guanshiyin Bodhisattva. This mantra can drive away evil and bring blessings.
