Caodong Sect, original from Yao Shan, is commonly considered as a branch of Qing Yuan lineage. But this was not accepted unanimously by all the Yao Shan offspring. He Shan, in the Dao Wu lineage from Yao Shan, insisted the equal position of Southern Mountain and He Ze, and did not acknowledge the status of Qing Yuan lineage. This suggested that Yao Shan might not originate from Qing Yuan.
