However, through identification, the distribution area of the Gelao ethnic group described in "Record of the Nine Heavens" is consistent with the local declaration after the mid-1980s (for example, it was declared that the birthplace of Gelao was in Wuchuan, while the core area of Yelang was ignored in Panjiang, Chishui, Hebei), deviating from the local history records of the Ming and Qing dynasties. Also, the description of the ancient song "Sue Genyou" in Gelao, and the grammatical errors of the classical Chinese and Gelao in "The History of Nine Heavens" contain many grammatical errors, hinting at the possibility of a modern-day forgery.
