Jia Zhigang was the author of The Four Grandmasters on the Warring States Period, which depicted a period of history during the Warring States Period. In the related settings of Joy of Life, there was the concept of the Four Great Grandmasters. Ye Qingmei had directly or indirectly created the Four Great Grandmasters who had transcended the martial arts realm. Among them, Ye Liuyun had relied on his own abilities to reach the Great Grandmaster realm and had not accepted Ye Qingmei's teachings. Ku He had become a Great Grandmaster because Ye Qingmei had given him the Tianyi Dao. Sigu Jian had obtained Ye Qingmei's Sigu swordsmanship manual and practiced with her to become a Great Grandmaster. The Qing Emperor had also reached the Great Grandmaster realm. However, this was different from Jia Zhigang's book about the Warring States Period. The two had the same concept (the Four Grandmasters).
