Wumenguan introduction: Wumenguan (Zen Hall) comes from the famous "wu" koan of Zhaozhou Zen Master. The courtyard is a place for monks to meditate and practice, and is not open to the public. On both sides are the abbot's and Wenchan's dormitories. In front of Wumen Pass, there are several gold and stone inscriptions from Berlin Zen Temple, such as the stone sutra stele from the Tianbao period of the Tang Dynasty, the three imperial edict stele from the Yuan Dynasty, etc.
