zhan zhao- Chinese custom

Zhan Zhao (展昭) was a man who lived during the period of Northern Song in the era of Emperor Renzong. He was the royal guard of the palace. He was assigned to work together with Bao Zheng who was a governor of Kaifeng city, the capital city of Northern Song. He was a very honest person who was good at martial arts. In his life he was known for serving Bao Zheng even more than being a royal guard of the imperial court. There are disputes between whether he really existed or whether he was a fictional character. People who argue for his non-fictionality point to a grave in a cemetery as proof that he was real.
