Shigu Commentary: The character is an ancient form of the character for call. If one refers to weeping as shouting in submission, then the first character is pronounced huo and the second character is pronounced fu. According to the Zhengzitong (Correction of Characters), it is a level tone shifting to a falling tone, entering the evening rhyme category. Shuowen Jiezi only lists the pronunciation as hu (falling tone). Various rhyme dictionaries include this character under the falling tone, making it identical to the character for call. Within the level tone category, the variant (hu) is sometimes written as this character; therefore, the falling tone should be considered correct. In the History of the Former Han (Qianhan), the passage in the Treatise on Astronomy is read in the falling tone, while the Biography of Guan Fu is read in the level tone; it is suspected that in ancient times, the two were interchangeable.
