Is there any fake calligraphy written by Daosheng Putuo?

No. The calligraphy works of the late Daosheng of Putuo Mountain are not printed, and authenticity is guaranteed. If they are fake, they will be fined 10,000 yuan. Mount Putuo, together with Mount Wutai in Shanxi, Mount Emei in Sichuan, and Mount Jiuhua in Anhui, is known as the four famous mountains of Chinese Buddhism. It is the dojo where Guanyin Bodhisattva teaches and educates all living beings. Since the establishment of Guanyin Dojo, there has been an endless stream of visitors.
