As the record of Daoxin’s teachings (The Five Gates of Daoxin) did not appear until the second decade of the eighth century, after Hongren’s record, its historical accuracy is in some doubt.
Karena catatan ajaran Daoxin (Lima Gerbang Daoxin) tidak muncul sampai dekade kedua abad kedelapan, setelah catatan Hongren, keakuratan sejarah masih dalam keraguan.
