Shandong is known as "one mountain, one water and one saint", which refers to Confucius, the Most Holy First Master. Confucius did not receive particularly great reverence during his life, but after his death, his status was increasingly noble, not only to seal the king, but also to be known as the Dacheng Most Holy First Master. The descendants of Confucius are also known as saints. They inherited the throne of Yansheng Duke for nearly a thousand years. Confucius is actually Yansheng Gong's Mansion. Confucius is a typical front office and post-office accommodation structure. The buildings in front are the places where Yan Shenggong handles government affairs, and the residential area and garden are behind. It is a good place to find the Ming and Qing rite system, and there is a good cultural and creative store.
