"Emperor Bai Yan of Zhou died on a snowy night ten years after he became emperor. This reckless emperor did not like luxury. After forcing the palace to seize the throne, he abandoned the gorgeous palace built by the previous dynasty. He slept in the Nine Dragon Pagoda in the imperial palace every night. When he died, he also crossed his legs on the futon in front of the tables in the stone room on the top of the tower, facing a portrait on the wall. If there are palace maids who have experienced the previous dynasty, they will definitely recognize that painting. The woman with the unparalleled color was the last noble concubine conferred by the former Emperor Jing. It turned out that Bai Yan finally followed that person and left no trace behind him. Therefore, all the mysteries about the founding emperor of the Zhou Dynasty were buried in the thick history books together with the portrait hanging on the nine-layer pagoda and hidden behind the seven-layer veil.
