Caodong school
The "Transmission of the Lamp" also claims that Tongan had no students himself. In other words, the Caodong school did not descend through Yunju as is commonly thought, but rather through another student of Dongshan Liangjie, namely Jufeng Puman. The scholar Morten Schlütter suggests that the lineage according to the "Transmission of the Lamp" is more likely correct because Dayang Jingshuan, who in Huihong's version of the lineage is a descendant of Yunju, is recorded in the "Transmission of the Lamp" as being descended through Jufeng Puman. Dayang was close with Wang Shu, one of the compilers of "Transmission of the Lamp", suggesting that it is unlikely that an error would have been made therein about his own lineage.
