What's the pronunciation of Zhong Er?

Regarding the pronunciation of "Zhong Er", the monarch of the State of Jin in the Spring and Autumn Period, Mr. Du Xiang, the dictionary room of the Institute of Linguistics of the Chinese Academy of Social Sciences, replied that the reason why Zhong Er got his name could not be found in the official records, and everyone was used to reading chóng. "Ci Yuan" includes "Zhong Er", and the pronunciation of "heavy" is also chóng.

The twenty-seventh chapter of History of the Eastern Zhou Dynasty says: "Zhong Er's eyes are heavy and his appearance is very different." Heavy means double. Some people suspect that Zhong Er may be called "Mother Worship" at first, but later he changed it to "Zhong Er" because it was not pleasant to hear. But this statement has no written basis. Lu Deming in the Tang Dynasty annotated Zhong Er's "heavy" in ancient books as "heavy, straight and straight". If you change the phonetic notation of the original book into modern Mandarin, you should read chóng.
