Tongan_Guanzhi
Tongan Guanzhi (Chinese: 同安觀志; Japanese: Dōan Kanshi) was a Zen Buddhist monk during the Five Dynasties and Ten Kingdoms period in 10th century China.[1] Traditionally, he is considered to be the student of Tongan Daopi. However, the basis for this belief comes from a text by Huihong called the Chanlin sengbao zhuan (Chronicle of the Sangha Treasure in the Groves of Chan), which was completed in 1119, many years after Tongan's death.[2]
