It's just a legend;
Because Xu Liang was born with a pair of white eyebrows, he was nicknamed "White Eyebrow Hero". There are five people including Shanxi Yan Xuliang, Yumian Zhuanzhu Bai Yunsheng and Xiaoxia Aihu. Xu Liang ranks third among them, so they are called the "Three Generals".
"White Eyebrow Hero" is a storytelling adaptation created and adapted by Shan Tianfang based on the traditional literary work "Xiao Wu Yi". It tells the legendary story of Shanxi Yan Xuliang, one of the "Five Small Righteousnesses" during the Northern Song Dynasty, who assisted Master Bao in catching errands and handling cases. It is divided into many parts such as "The Birth of Xu Liang" and "The Meeting of Dragon and Tiger". The image of Xu Liang in the book: eight feet tall, with drooped eyes, a hooked nose, raised mouth corners, two white eyebrows; water snake waist, three curves, and a bulging naan bag on the back. On the back is a large golden ring sword and a green dragon sword.
