Textual research: In the Dialects (Fangyan) by Yang Zi, it is written as between the regions of Chen and Chu, when people or animals give birth to twins, it is called lizi. In the regions of Qin and Jin, it is called lianzi. From the mountain passes eastward, it is called luan. The original text has been corrected where Chen replaced East, birth replaced life, and lizi replaced the variant form.
